4. X-ray diffraction (XRD): used to analyze the crystallinity and crystal structure of materials.

5. Scintillation counter: used to measure the radiation intensity and energy spectrum in radioactive samples.

6. Optical microscope (OM): used to observe the external morphology and organizational structure of materials.

16. Confocal Laser Microscopy (CLSM): Provides high-resolution three-dimensional images and surface morphology.

17. Thermal expansion coefficient measuring instrument: used to measure the length expansion or contraction of materials under temperature changes.

18. Surface plasmon resonance sensor (SPR): used for real-time monitoring and analysis of biomolecular interactions.

19. Stable isotope analyzer (IRMS): used to measure the ratio of stable isotopes in samples, such as carbon, nitrogen and oxygen.

20. Thermal analysis/thermogravimetry/differential scanning calorimetry (STA/DSC/TGA) coupling instrument: used to simultaneously measure the thermal stability, heat capacity and thermal degradation behavior of materials.

Microstructural analysis project

Non-metallic inclusion assessment: Check steel for important purposes (such as rolling bearing steel, The quantity, shape, size and distribution of non-metallic inclusions (spring steel, stainless steel, high-speed steel, alloy steel, mold steel, etc.) are helpful for companies to control product performance and improve product quality.

Macroscopic metallographic structure analysis: Evaluate whether there are voids and inclusions in products (such as cast iron, steel, non-ferrous metal parts, welded parts, etc.) , such as the structural direction of the die casting and whether there are obvious defects such as incomplete penetration of the weld.

Metal average grain size evaluation: Check the material grain size and evaluate the material performance.

X-ray diffractometer technology (XRD): Use XRD to conduct phase identification, crystallinity analysis, lattice parameters, microscopic analysis of materials Stress measurement, average particle size measurement of nanoparticles, etc. can help companies understand the performance and quality of materials in all aspects of R&D, production, and use.

Micrometallographic structure analysis: Mainly used to inspect metal materials (such as cast iron, steel, copper alloy, aluminum alloy, magnesium alloy , nickel alloy, titanium alloy, etc.) microstructure composition to evaluate the quality of heat treatment.

Carburizing/nitriding/hardened layer depth measurement: Inspection components (carburizing, nitriding, decarburization, carbonitriding Surface treated steel parts, induction hardened steel parts, etc.) after surface carburizing, nitriding or hardening treatment, penetration depth and structural changes.

What are the uses of BAIJIAN analysis reports? What problems can it help you solve?

1. Sales reports. (Sales need to provide third-party testing reports to make their products more unique, let the product data speak for themselves, and make customers more confident in the quality of their products.)

2. Industrial diagnostic report. (When encountering some difficult problems about ingredients, use third-party testing data to find the cause of the problem and solve the problem in a timely manner.)

3. Product performance improvement. (Discover problems with your own products through comparison of third-party testing data, improve product problems, improve quality, and reduce production costs)

4. Use of scientific research paper data.

5. Products are used for import and export.

6. Product development and use. (Want to develop new products and shorten the R&D cycle and R&D costs)
