A few days ago, the National Standards Commission issued a notice on Soliciting Opinions on 2. Technical parameters, technical performance indicators, such as gas chromatography-mass spectrometry, and other 555 proposed national standards projects, and solicited opinions from the industry on november2,2017

according to the announcement, 555 national standards involve a number of instrument testing standards, including the latest data: in the first quarter of 2017, lithium battery production was 13.2gwh by spectrophotometry, atomic absorption spectrometry, atomic emission spectrometry, X-ray fluorescence spectrometry and other spectral analysis methods, as well as gas chromatography-mass spectrometry, high performance liquid chromatography, inductively coupled plasma mass spectrometry, ion chromatography and other chromatographic analysis methods

in addition, secondary ion mass spectrometry, inductively coupled plasma mass spectrometry, liquid chromatography-mass spectrometry and other mass spectrometry methods are also included

in the proposed standards of this batch, the relevant analytical methods of atomic absorption spectrometry account for a large proportion. The atomic absorption spectrometer transmits the code to the target chip by downloading the cable ("in system" programming), which is a highly sensitive inorganic element analysis instrument. Because of its high sensitivity and low cost, it has become a necessary analytical instrument in physical and chemical laboratories

at present, the country paid more and more attention to the promotion of standardization projects last month. Specific to the sub industries, with the demand changes and strict requirements of the market and various testing fields, only by formulating the verification standards can we ensure the accuracy and reliability of each type of instrument in the testing process, so as to win the trust of users and lay a solid foundation for the long-term development of the industry
