浩瀚淮山、党参10种中药材中二氧化硫残留量测定气相色谱仪GC7990

Sulfur has disinfection, preservation, bleaching, anti-corrosion effect, for some water content is high, difficult to dry, easy moldy, metamorphic, insects of traditional Chinese medicine, traditional Chinese use of sulfur fumigation of rough processing methods, the application of a longer history, There is no easy and cost-effective alternative. In recent years, there are unscrupulous businesses for the pursuit of commercial interests, the use of excess sulfur fumigation of Chinese herbal medicines, resulting in Chinese herbal medicines in sulfur dioxide (SO2.
Tengzhou Xiangying Analytical Technology Co., Ltd. uses headspace gas chromatography, the determination of Chinese yam, Codonopsis 10 kinds of Chinese herbal medicines in the residual sulfur dioxide, easy to master, reproducible, and can be used as Chinese herbal medicine sulfur dioxide residue detection method.
硫黄具有消毒、保鲜、漂白、防腐的作用,对于部分含水量高,难以干燥,易发霉、变质、生虫的中药材,我国传统习用硫黄熏蒸的粗加工方法,其应用历史较长,目前尚无简便易行和经济有效的替代方法。近年来有不法商家为追求商业利益,使用超量硫磺熏蒸中药材,致使中药材中二氧化硫(SO2。
