烷基糖苷(APG)是一種重要的非離子表面活性劑，其含量的準(zhǔn)確測定對于質(zhì)量控制至關(guān)重要。
樣品前處理
衍生化：由于烷基糖苷極性大、沸點高，直接進樣分析困難，通常需進行硅烷化衍生處理
常用衍生化試劑：BSTFA(雙三甲基硅基三氟乙酰胺)+TMCS(三甲基氯硅烷)
衍生化條件：60-80℃反應(yīng)30-60分鐘

Alkyl glycosides (APG) are important non-ionic surfactants, and accurate determination of their content is crucial for quality control.
Sample pre-treatment
Derivatives: Due to the high polarity and boiling point of alkyl glycosides, direct injection analysis is difficult and usually requires silanization derivatization treatment
Common derivatization reagents: BSTFA (bis (trimethylsilyltrifluoroacetamide)+TMSC (trimethylchlorosilane)
Derivative conditions: reaction at 60-80 ℃ for 30-60 minutes
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. is an analytical method for determining the composition of alkyl glycosides using gas chromatography (GC). As an internal standard, the relative weight correction factors of glycerol, dodecanol, d-glucose, butyl monoglycoside, and dodecyl monoglycoside were determined separately, and the various components in alkyl glucoside were quantified. The sample measurement data showed that the relative error was within 7.5%, and the coefficient of variation did not exceed 2
