Degradation dynamics and final residues of hymexazol in Polygonum capitatum Buch were estimated by GC-FPD with pre-column derivatization. 採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態和最終殘留量。
Autosampler can be programmed into the sample, used for pre-column derivatization, automatic pre-column sample dilution, automatic mixing and other complex sampling methods. 自動進樣器可進行編程進樣,用於進行柱前衍生,柱前樣品自動稀釋,自動混合等複雜進樣方式。
