New National Standard for Sulfur Dioxide in Food (Chinese Pharmacopoeia Method for Testing Sulfur Dioxide in Traditional Chinese Medicine) Specialized Matching Instruments: ST109AST109BBST109CST109D Full Series Standard Matching Automatic Reagent Addition, Automatic Nitrogen Blow Control Function (National First Innovation)!!!

Development Background:

      With the release of the new national standard GB5009.34-2022 "Determination of Sulfur Dioxide in Food", the testing methods for sulfur dioxide in food and the Chinese Pharmacopoeia for traditional Chinese medicine materials are now largely the same. Jinan Shengtai Technology has developed four specialized testing instruments—ST109A, ST109B, ST109C, ST109D—based on the new national standard and pharmacopoeia methods. Among them, ST109A is the first fully automated specialized testing instrument in China.

Fully compliant with the new national standard for sulfur dioxide in food and the 2016 & 2020 editions of the Chinese Pharmacopoeia methods.
