The 13 standard substances newly developed by Guangdong Metrology Institute passed the appraisal
[ Instrument Network Instrument Development ] Recently, 13 standard substances newly developed by the Guangdong Metrology Institute were identified by the State Administration of Market Supervision. Up to now, there have been 86 national secondary standard materials successfully developed by Guangdong Metrology Institute, which has well supported the supervision and management of food safety, environmental monitoring and instrument calibration analysis in Guangdong Province.
The newly developed 13 standard materials are mainly three kinds of ferromagnetic material Curie temperature standard materials series (GBW(E)130655-GBW(E)130657), hydrogen sulfide in nitrogen, ammonia in nitrogen, and four in nitrogen. There are 10 kinds of standard gas series such as fluoroethane (GBW(E)062604-GBW(E)062613), which can be applied to the Curie temperature test process of ferromagnetic materials, thermal analyzer, hydrogen sulfide analyzer and alarm in nitrogen, Calibration of instruments such as ammonia analyzers and alarms, refrigerant leak detectors, etc.
Standard material, as a measuring instrument, is the “chemical weight†for qualitative and quantitative test analysis. It is also the basis for scientific research, method research and evaluation, quality control and assurance, value transfer and traceability.
