Application

Two different and accurate analytical methods, namely high-performance liquid chromatography (UV detector) and gas chromatography (FID detector), are used to determine the purity of standard materials. By using measurement methods and measuring instruments that meet the requirements of metrology, ensure their traceability.

Uniformity inspection and stability inspection

According to the requirements of JJF1343-2012 "General Principles and Statistical Principles for Calibration of Reference Materials", samples were randomly selected and packaged. Gas chromatography (FID) was used to test the uniformity and stability of purity, and the test results showed good uniformity and stability.

The stability tracking inspection of the standard substance at home is valid for 3 years from the date of self calibration. The research and development unit will continue to monitor the stability of the standard substance, and if any changes are found within the validity period, users will be notified in a timely manner.
