Engineering Center Test Instruments


Powder comprehensive performance tester

Brand model number:Baxter, BT-1000

The main purpose:BT-1000 powder comprehensive performance tester is a multi-functional powder characteristic tester. The test items of the instrument include the tap density of the powder, the bulk density, the angle of repose, the angle of the flat plate, the angle of collapse, and the degree of dispersion. Calculation items include difference angle, porosity compressibility (compression rate), fluidity index, jet index, etc.

Sample requirements:Fine particles or powder









Oxygen, nitrogen and hydrogen analyzer

Brand model: Beijing Steel Research Nack, ONH-3000

Main purpose: to analyze the content of oxygen, nitrogen and hydrogen in steel, nonferrous metals, ceramics and other inorganic materials

Sample requirements: fine particles or powder

Analysis range: low oxygen <1ppm-0.5% *>, high oxygen <0.5% -20% *>, low nitrogen <1ppm-2% *>, high nitrogen <0.5% -50% *>, hydrogen <0-0.1 %>

Analysis accuracy: O <1ppm or 1% *>, N <1ppm or 1% *>, H <0.2ppm or 2%>





Atomic absorption spectrophotometer (AAS)

Brand model: Beijing General Analysis, A3F-13

Main application: The flame atomization method is easy to operate, has good reproducibility, large effective optical path, and has high sensitivity to most elements, so it is widely used.

Principle: Atomic absorption is the absorption of light of a specific wavelength by the outer electrons of atoms or ions, so that an energy level transition occurs, and the concentration of the solution is calibrated according to the intensity of the absorbed light.

Sample requirements: The sample can be decomposed completely, and the sample can be kept relatively stable for a long time after decomposition.

Performance: characteristic concentration, Ba <0.15 μg / ml / 1%










Laser particle size analyzer

Brand model: Malvern Mastersizer 3000

Main purpose: Used for high-precision particle size analysis, suitable for various metal powders: such as aluminum powder, zinc powder, and other non-metal powders, such as catalysts, cement.

Principle: Light is hindered by particles during propagation, causing diffraction and scattering. Diffraction light and scattered light spatial (angle) light wavelength distribution is related to pore or particle size. According to Mie theory, the size and distribution of particle size can be derived.

Sample requirements: powder

Detection range: 10 nm-3500 μm







Optical microscope

Brand model: Cai Kang DMM-330C

Main purpose: used to observe the surface morphology of products, suitable for various metal powders.

Principle: Principles of Optical Imaging

Sample requirements: granular or solid

Detection range: 50 times to 2000 times










Microwave digestion apparatus

Brand model: MARS6

Main application: assist ICP and atomic absorption spectrophotometer for element analysis, and can complete the pretreatment of most organic / inorganic / liquid / solid samples.

Principle: MARS uses microwave energy to heat the sample. Compounds such as water and other polar liquids can quickly absorb microwave energy. The sample is placed in a microwave-transmissive digestion tank. Polar liquids and ionic solutions (usually acids) can be quickly heated and the pressure increased, so that the sample can be digested in a short time.

Sample requirements: fine particles or powder








Full spectrum direct reading plasma emission spectrometer

Brand model: Liman-Lebos Prodigy 7

Main application: Quickly carry out qualitative, semi-quantitative and precise quantitative analysis of trace elements in various unknown samples

Detection range: can measure all metal elements and some non-metal elements

Wavelength range: 165-1100 nm

 Sample requirements: clear, no suspended matter, stable solution
