Electron Paramagnetic Resonance (EPR) spectroscopy remains a cornerstone in analyzing unpaired electrons, whether in free radicals, transition metals, or defect sites. However, when selecting between X-band and Q-band EPR systems, researchers often face a classic dilemma: how to match performance needs with budget realities.

Here’s a practical breakdown to help European labs and research teams navigate this decision—and why many are choosing flexible EPR systems like CIQTEK’s to get the best of both worlds.

Performance Trade-Offs: Sensitivity vs. Resolution

X-band EPR (≈9.5 GHz) is by far the most commonly used band. It offers a great balance of sensitivity, hardware availability, and ease of sample handling. It’s particularly suited for general-purpose applications:

• Organic radicals

• Transition metal complexes

• Spin labeling in biomolecules

In contrast, Q-band EPR (≈35 GHz) provides higher spectral resolution due to increased Zeeman splitting and better orientation selectivity. However, this comes with practical considerations—cryogenic compatibility becomes more critical, and sample tuning can be more sensitive.

For labs doing high-resolution studies of biological macromolecules or probing fine structural changes in solid-state samples, Q-band can offer real advantages—if the infrastructure is ready.

Typical Price Ranges in Europe

Budget plays a decisive role. Based on recent European procurement data:

• X-band CW EPR systems typically range from €100,000 to €250,000, depending on features like variable temperature accessories or pulse capability.

• Q-band systems start around €250,000 and can exceed €500,000, especially when combined with pulsed capabilities and cryogenic sample handling.

This cost gap makes X-band the default choice for most labs—especially teaching labs, material science departments, or first-time EPR users.

CIQTEK benchtop EPR system is a strong performer here. With X-band capability, built-in temperature control, and a space-saving design, it has been installed in both US and EU university labs where compactness and quick setup are key priorities.

Use-Case Match: Materials vs. Biological Samples

X-band covers a broad range of material research, from battery cathodes to polymer radicals, while Q-band offers finer insight into g-tensor anisotropy, valuable in protein structure, spin-labeled enzymes, and advanced pharmacological studies.

Labs working with diverse sample types may benefit from EPR systems that are modular or upgradable, depending on research evolution.

CIQTEK’s CW-Pulse EPR system supports both CW and time-resolved measurements at X-band and is designed with future expansion in mind, including Q-band add-ons in pipeline development.

Electron Backscatter Diffraction (EBSD) is a widely used microscopy technique in material science. It analyzes the angles and phase differences of the backscattered electrons produced when a sample interacts with a high-energy electron beam to determine key characteristics such as crystal structure and grain orientation. Compared to a traditional Scanning Electron Microscope (SEM), EBSD provides higher spatial resolution and can obtain crystallographic data at the sub-micrometer level, offering unprecedented details for analyzing material microstructures.

 

Characteristics of the EBSD Technique

 

EBSD combines the microanalysis capabilities of Transmission Electron Microscope (TEM) and the large-area statistical analysis capabilities of X-ray diffraction. EBSD is known for its high-precision crystal structure analysis, fast data processing, simple sample preparation process, and the ability to combine crystallographic information with microstructural morphology in material science research. SEM equipped with an EBSD system not only provides micro-morphology and composition information but also enables microscopic orientation analysis, greatly facilitating the work of researchers.

 

Application of EBSD in SEM

 

In SEM, when an electron beam interacts with the sample, various effects are generated, including the diffraction of electrons on regularly arranged crystal lattice planes. These diffractions form a "Kikuchi pattern," which not only contains information about the symmetry of the crystal system but also directly corresponds to the angle between crystal planes and crystallographic axes, with a direct relationship to the crystal system type and lattice parameters. This data can be used to identify crystal phases using the EBSD technique, and for known crystal phases, the orientation of the Kikuchi pattern directly corresponds to the orientation of the crystal.

 

EBSD System Components

 

To perform EBSD analysis, a set of equipment including a Scanning Electron Microscope and an EBSD system is required. The core of the system is the SEM, which produces a high-energy electron beam and focuses it on the sample surface. The hardware part of the EBSD system usually includes a sensitive CCD camera and an image processing system. The CCD camera is used to capture the backscattered electron images, and the image processing system is used to perform pattern averaging and background subtraction to extract clear Kikuchi patterns.

 

Operation of the EBSD Detector

 

Obtaining EBSD Kikuchi patterns in SEM is relatively simple. The sample is tilted at a high angle relative to the incident electron beam to enhance the backscattered signal, which is then received by a fluorescent screen connected to a CCD camera. The EBSD can be observed directly or after amplification and storage of the images. Software programs can calibrate the patterns to obtain crystallographic information. Modern EBSD systems can achieve high-speed measurements and can be used in conjunction with Energy-Dispersive X-ray Spectroscopy (EDS) probes to perform compositional analysis while rapidly obtaining sample orientation information.

 

Sample Preparation Principles

 

For effective EBSD analysis, sample preparation needs to follow certain principles, including the absence of residual stress, a flat surface (mechanical polishing), cleanliness, suitable shape and size, and good conductivity. The sample preparation process may involve ion etching, polishing, and other steps to ensure that the sample surface is suitable for EBSD analysis.

 

EBSD Calibration and Surface Scanning

 

Calibration is a critical step in the EBSD analysis process, ensuring an accurate correspondence between the Kikuchi patterns and crystallographic parameters. Surface scanning is another important application of EBSD technology, allowing researchers to perform extensive crystallographic analysis on the sample surface, thereby obtaining a comprehensive view of the material's microstructure.

Focused Ion Beam (FIB) technology has become an essential part of modern technological advancements, particularly in semiconductor manufacturing and nanofabrication. While FIB technology is well-known, its history and development are not widely known. Focused Ion Beam (FIB) is a micro-cutting instrument that uses electromagnetic lenses to focus an ion beam into a very small area. FIB involves accelerating ions from an ion source (most FIBs use Ga, but some devices have He and Ne ion sources) and then focusing the beam onto the surface of the sample.

CIQTEK DB550 Focused Ion Beam Scanning Electron Microscope (FIB-SEM) 

 

Origin of FIB Technology

 

Since the 20th century, nanotechnology has rapidly developed as an emerging field in science and technology. Currently, nanotechnology represents one of the forefront areas of scientific and technological advancement and has significant implications for economic and social development as a national strategy. Nanostructures have unique properties due to their structural units approaching the coherence length of electrons and the wavelength of light, leading to surface and interfacial effects, size effects, and quantum size effects. They exhibit many novel characteristics in electronics, magnetism, optics, and mechanics, and hold enormous potential in high-performance device applications. The development of novel nanoscale structures and devices requires the advancement of precise, multidimensional, and stable micro-nanofabrication techniques. Micro-nanofabrication processes are extensive and commonly involve techniques such as ion implantation, photolithography, etching, and thin film deposition. In recent years, with the trend of miniaturization in modern manufacturing processes, Focused Ion Beam (FIB) technology has increasingly been applied in fabricating micro-nano structures in various fields, becoming an indispensable and important technique in micro-nanofabrication.

FIB technology is developed based on conventional ion beam and focused electron beam systems and is essentially the same. Compared to electron beams, FIB scans the sample surface using an ion beam generated by an ion source after acceleration and focusing. Since ions have much greater mass than electrons, even the lightest ions, such as H+ ions, are more than 1800 times the mass of electrons. This enables the ion beam to not only achieve imaging and exposure capabilities similar to electron beams but also utilize the ion's heavy mass to sputter atoms from solid surfaces, making it a direct processing tool. FIB can also induce atoms to deposit onto the sample material surface by combining with chemical gases. Therefore, FIB is a widely applicable tool in micro-nanofabrication.

 

Development of Ion Sources

 

In the development of FIB technology, the advancement of high-brightness ion sources has been crucial. Early gas ion sources and Liquid Metal Ion Sources (LMIS) laid the foundation for FIB technology. In 1974, Seliger and Fleming first used a gas ion source for maskless ion implantation and resist exposure, confirming the potential of this technology. Subsequently, Orloff and Swanson developed the gas field ion source, which had high resolution but limited industrial application due to the requirement of low temperatures. The Liquid Metal Ion Source, on the other hand, was more successful due to its high ion brightness and ease of operation, laying the foundation for modern FIB systems based on Ga LMIS.

 

Applications of FIB Technology

 

FIB technology finds a wide range of applications, including ion implantation, milling, surface chemistry, lithography, materials micro-analysis, and scanning ion microscopy. In 1987, J. Melngailis published a comprehensive review of FIB applications, highlighting the potential of FIB technology in multiple fields.

LR41, LR43 and LR44 are all alkaline coin cell batteries, but they have certain differences in specifications and uses. Do you know the applications of these batteries in daily life? This article will analyze the differences between them in detail and explain why they cannot be used interchangeably.

 

What are LR43 coin cell batteries?

The LR43 battery is an alkaline button cell with a nominal voltage of 1.5V and a usable temperature range of 0°C to 60°C, with an optimal operating temperature of approximately 20°C. This battery is popular for its durability, high capacity, high energy density, and stable and reliable performance.

LR43 button cell batteries are used in a variety of devices, including watches, electronic toys, remote controls, and calculators. LR43s are also interchangeable with other battery types, such as SR43, AG12, LR1142, 386, 301, 186, etc. However, it is important to note that although LR44 and LR43 are the same size, their chemical compositions are different and therefore not fully compatible. For example, SR43W, SR43, SR43SW, 386, 301, and AG12 are silver oxide button cells, while LR43 is an alkaline button cell.

It is worth mentioning that LR43 batteries do not contain mercury, are environmentally friendly and safe. Since the production standards of different brands may be slightly different, it is recommended to carefully check the product information before purchasing to ensure that it meets the needs of your device. 

 

LR44 battery replacement

 

 

Batteries that are comparable in size and capacity to the LR44 may be labeled differently depending on the manufacturer. Direct replacements for the LR44 include the Duracell 76A, Energizer A76, and AG13 batteries. Despite the different names, these batteries are identical replacements for the LR44 and are interchangeable. 

There are also other batteries with the same size as the LR44 but with different chemistries, such as the SR44, SR44SW, 357, and 303 silver oxide batteries. These batteries feature a more stable voltage output and are suitable for devices that require low power consumption and long operation, such as watches or certain medical devices.

One of the most common questions is, "Are LR44 and 357 the same?"

While 357 batteries and LR44 are similar in size, they differ in chemistry, cost, and performance. For example, 357 uses silver oxide technology, which provides longer-lasting power for low-power devices, while LR44 is primarily alkaline and is suitable for general-purpose electronic devices. 

 

What is an LR41 battery?

 

 

The LR41 is a small alkaline button cell battery that is widely used in electronic devices. Many well-known brands, such as Toshiba and Maxell, produce this type of battery. In addition, some smaller brands, such as Tianqiu, also offer LR41 batteries.

It's worth noting that similar sized batteries from brands such as Energizer may use different chemistries, such as silver oxide instead of alkaline, and therefore may vary in performance and usability.

Whether it’s your car key fob, digital watch, or kitchen scale, coin cell batteries are an important source of power for these devices. The CR2032 and CR2025 are two of the most common types, but many people don’t know the difference between them. Does size matter? What are the performance differences? How do you choose the best one for your device?

This article will take a deep dive into the characteristics of CR2032 and CR2025 batteries to help you make an informed choice.

 

Part 1. What does CR stand for?

First, let’s understand what the “CR” prefix means. “CR” stands for lithium coin cell, which uses lithium manganese dioxide (LiMnO2) as the main chemical component. This chemical material gives the battery a stable output voltage and provides a long storage life of typically 5 to 10 years.

In contrast, other coin cell batteries may use different chemistries, such as:

• “LR” (alkaline battery)

• “SR” (silver oxide battery)

So when you see the “CR” logo, you know it’s a lithium battery designed for low-power, long-life applications.

 

Part 2. What is a CR2032 battery?

 

 

The CR2032 lithium coin cell battery is one of the most widely used button batteries, favored for its balanced size and capacity. As you can see from the naming convention:

• The first two digits "20" represent the battery's 20 mm diameter

• The last two digits "32" represent the battery's 3.2 mm thickness

CR2032 button cell batteries are highly regarded for their high capacity, with a voltage of 3v, typically between 210 mAh and 240 mAh, making them ideal for devices that require longer-lasting power. From medical devices like blood glucose monitors to everyday items like car key fobs and small remote controls, CR2032 batteries provide reliable power, even in colder conditions where other batteries may fail.

 

Part 3. Understanding CR2025 Batteries

 

 

The CR2025 is also part of the CR series of button batteries, and the "2025" in its name means:

• Diameter: 20 mm

• Thickness: 2.5 mm (slightly thinner than the CR2032)

Due to their smaller capacity and 3v voltage, typically between 210 mAh and 240 mAh, CR2025 button cell batteries may not last as long as their thicker counterparts, especially in devices that require a steady supply of power. However, they are still very effective in low-power devices such as watches, small remote controls, and some medical devices such as thermometers.

 

Part 4. CR2032 vs. CR2025: Which is Better?

There is no absolute "better" choice when it comes to choosing between a CR2032 and a CR2025. It really depends on your specific needs. If your device requires a battery with a larger capacity and longer life, such as a car key fob or medical device, then the CR2032 button cell battery would be your first choice. On the other hand, if your device has a more compact battery compartment or requires minimal power consumption, then a CR2025 button cell battery may be a better fit.

 

Part 5. How do I choose the right battery?

 

 

The choice between a CR2032 or CR2025 depends largely on the power requirements of the device and the available space in the battery compartment. For example, if your device manual specifies the use of a CR2025, it may be due to size constraints. In this case, using a CR2032 (even if it has a higher capacity) may not be a good fit. When replacing batteries, it is recommended to refer to the device manual to ensure that the selected battery meets the requirements.

 

Part 6. Are CR2032 and CR2025 interchangeable?

In many cases, it is not possible to replace a CR2025 with a CR2032, but this depends on the device's battery compartment. Since the CR2032 is thicker, it may not fit into a compartment designed for the thinner CR2025.

 

Part 7. Are CR2032 and CR2025 rechargeable?

Generally, CR2032 and CR2025 batteries are disposable and not rechargeable. If they become depleted, they should be properly recycled.

 

In general, it is best to use the battery type specified in the device manual for optimal performance and safety.

To test your CR2450 button cell battery, use a multimeter set to DC voltage. A healthy battery should read close to 3 volts. If it reads significantly lower, it needs to be replaced. Some devices have built-in battery indicators; refer to the device manual for specific testing procedures. 

 

Signs of a CR2450 lithium manganese battery failure

Watch for the following indicators of battery failure:

• Dimming of the device display or LED

• Intermittent device operation

• Frequent low-battery warnings

• Unusual behavior of the electronic device  

 

Can the CR2450 be replaced with another battery type?

No. Use batteries that match the size (24mm wide, 5mm thick) and voltage (3.0V). Similar types (such as BR2450) may be suitable for low-drain applications, but have different chemistry and lower capacity. 

 

Safety precautions when using CR2450 coin cell batteries:

• Keep button batteries out of the reach of children to prevent accidental swallowing, which may cause serious choking risks or internal damage.

• Avoid exposing the battery to high temperatures, do not puncture it or attempt to charge it to prevent safety hazards from short circuits or leakage.

• It is recommended to store the battery in a cool, dry environment to maintain its optimal performance and extend its life.
