Special instruments for the new national standard food sulfur dioxide (Chinese Pharmacopoeia method for testing traditional Chinese medicine sulfur dioxide): ST109AST109BBST109CST109D are equipped with automatic reagent addition and automatic nitrogen blowing control functions (the first in the country) as standard! ! !

R&D Background:

With the promulgation of the new national standard GB5009.34-2022 "Determination of sulfur dioxide in food" , the determination methods of sulfur dioxide in food and sulfur dioxide in traditional Chinese medicine in the "Chinese Pharmacopoeia" are roughly the same. Jinan Shengtai Technology has developed four special testing instruments , ST109A, ST109B, ST109C, and ST109D , based on the new national standard and pharmacopoeia methods. Among them, ST109A is the first fully automatic detection instrument in China.

It fully complies with the new national standard for food sulfur dioxide and the methods of the 2016 and 2020 editions of the "Chinese Pharmacopoeia".
