Equipment
The R&D center currently has X-ray diffractometers, specific surface area analyzers, X-ray fluorescence spectrometers, gas chromatographs, laser particle size analyzers, X-rays, atomic absorption spectrophotometers and inductively coupled plasma high-frequency emission spectrometers.
1. X-ray diffractometer (XRD)
The X-ray diffractometer uses the principle of diffraction to measure the polycrystalline phase, accurately perform phase analysis (qualitative or quantitative), determination of unit cell parameters, determination of lattice distortion, determination of crystallinity and Rietveld analysis, etc. Simple and flexible, reliable data, suitable for a variety of polycrystalline phase analysis, our company is mainly used for the analysis of the phase and crystal structure of battery materials.
2. specific surface area analyzer
Specific surface analyzers are specialized equipment for detecting the specific surface area of particulate matter. The specific surface area is the surface area per unit mass of matter (m2/g), which is one of the most important physical properties of the powder material. Our company is mainly used for testing the specific surface area of powder main materials and additives, and monitoring the incoming material quality of powder materials.
3. X-ray fluorescence spectrometer (XRF)
X-ray fluorescence spectrometer is an analytical method based on polarization energy dispersive (ED-XRF), which can analyze solid, powder, liquid and other samples. The analysis range is Be to U. In recent years, X-ray fluorescence spectrum analysis has been continuously expanded in various industries. Most of the analytical elements can be analyzed and have the characteristics of fast analysis, wide measurement range, low interference, and no sample damage. Our company is mainly used for the detection of harmful substances in the EU ROHS Directive, and rapid analysis of material element composition and coating thickness analysis.
4. gas chromatography (GC)
Chromatography (GC) is based on the difference in partition coefficient between the mobile phase and the stationary phase. When the sample is carried into the column by the carrier gas, the process is repeated multiple times between the two phases, because the relative components are fixed. The effects of dissolution, adsorption, permeation or ion exchange have different effects on the retention ability. After the column, they are separated from each other, flow out of the column in order, enter the detector, and display on the recorder. The spectrum of the components. According to the order, the peak height or peak area can distinguish the components and calculate the content of each component. Our company uses GC to test the gas composition and content of the battery during charging and discharging.
5. laser particle size analyzer
The principle of the laser particle size analyzer is that the laser beam encounters the particle sample in the sample cell during the propagation process, and the concentrated beam is scattered to the detector and converted into an electrical signal output. It is widely used to test the particle size of various non-metal powders, metal powders (such as copper powder, alloy powder, rare earth metal powder, etc.). It has good repeatability, wide test range and fast test. Our company is mainly used for powder. Test the particle size of the bulk material to verify the quality of the powder material.
6. X-perspectometer
X-ray - The fluoroscopy uses X-ray penetration to analyze the internal structure of the material. It is widely used to see through bone, non-metal, thin metal, plastic and other items. Our company is mainly used to observe the internal structure of the battery.
7. Atomic absorption spectrophotometer
The atomic absorption spectrophotometer uses the element to be tested to be heated and atomized to become the ground state atomic vapor, and selectively absorbs the characteristic radiation emitted by the hollow cathode lamp. The absorbance is measured, and the absorption intensity and the content of the measured component in the test solution are determined. In proportion, the element content is calculated according to the Lange-Beer law. It is mainly used for the analysis of trace element impurities. It has two main advantages: high sensitivity and good selectivity. Our company is mainly used for the analysis of trace impurity elements in battery materials. Accurate testing of hazardous metal elements in the ROHS Directive.
8. Inductively Coupled Plasma High Frequency Emission Spectrometer (ICP-OES)
Inductively coupled high-frequency plasma emission spectroscopy (ICP-OES) analysis is a method of qualitatively and quantitatively analyzing a sample by exciting it in a plasma source, causing the element to be detected to emit radiation of a characteristic wavelength, and measuring the intensity by spectrometry. ICP-OES has the advantages of fast analysis speed, high sensitivity, good stability, wide linear range, small matrix interference, and simultaneous analysis of multiple elements. Now widely used in geology, environmental protection, chemical, biological, pharmaceutical, food, metallurgy, agriculture and other industries, our company is mainly used to analyze the elemental composition and content of battery materials.
