Product Introduction

Traditional Chinese Medicine Sulfur Dioxide Residue Analyzer

Compliant with the legal testing methods of the 2015 edition of the Chinese Pharmacopoeia

Can be used for pre-treatment of sulfur dioxide residue detection in traditional Chinese medicinal materials and decoction pieces according to the methods specified in the Chinese Pharmacopoeia.

The 2015 edition of the Chinese Pharmacopoeia specifies three detection methods for sulfur dioxide, including acid-base titration, gas chromatography, and ion chromatography. Gas chromatography and ion chromatography have the advantages of high sensitivity and strong specificity, but the expensive equipment is not conducive to the promotion and use of grassroots drug testing systems; The acid-base titration method has the advantages of simple installation and low cost, and is a legal detection method specified in the pharmacopoeia.
