Degradation dynamics and final residues of hymexazol in Polygonum capitatum Buch were estimated by GC-FPD with pre-column derivatization. 采用柱前衍生氣相色譜法測定廣枯靈中惡霉靈在中藥材頭花蓼上的殘留消解動(dòng)態(tài)和最終殘留量。
Autosampler can be programmed into the sample, used for pre-column derivatization, automatic pre-column sample dilution, automatic mixing and other complex sampling methods. 自動(dòng)進(jìn)樣器可進(jìn)行編程進(jìn)樣，用于進(jìn)行柱前衍生，柱前樣品自動(dòng)稀釋?zhuān)詣?dòng)混合等復雜進(jìn)樣方式。
