Physical and chemical laboratory
Our laboratory is a professional technical department under the Metrology and Calibration Business Division of LETRI. Our laboratory is mainly oriented to the field of chemical metrology and biotechnology testing, providing measurement calibration, testing and technical research and development support for enterprises, scientific research institutes, colleges and universities, etc. The fields involved include:
● Calibration and detection of common physical and chemical instruments
● Calibration and detection of spectral/chromatographic/mass spectrometric analyzer
● Gas safety monitoring instrument detection
The laboratory is located in the physical and chemical laboratory and gas detection laboratory on the second floor of Building 5, New Technology Industrial Park, No. 98 Hengshan Road, High tech Zone, Suzhou.
The laboratory has more than 10 members, mainly including a technical team composed of masters and university undergraduates. Most of the team members are young and middle-aged people. It is a vigorous, well-trained and high-quality team with extremely strong professional quality and working ability.
It has passed more than 10 measurement standards (gas chromatograph verification device, combustible gas detection alarm verification device, etc.).
Approved and authorized by CNAS, it has passed more than 100 metrological calibration projects. Its calibration capability covers almost all analytical instrument projects such as spectrum, chromatography, mass spectrometry and gas analysis. It is one of the laboratories with the most complete calibration and detection projects in East China.
With the approval and authorization of CMA, the detection of alloy element analysis, laboratory water, clean workbench, biosafety cabinet, clean workshop, etc. has been established.
