烷基糖苷(APG)是一种重要的非离子表面活性剂,其含量的准确测定对于质量控制至关重要。
样品前处理
衍生化:由于烷基糖苷极性大、沸点高,直接进样分析困难,通常需进行硅烷化衍生处理
常用衍生化试剂:BSTFA(双三甲基硅基三氟乙酰胺)+TMCS(三甲基氯硅烷)
衍生化条件:60-80℃反应30-60分钟
浩瀚色谱(山东)应用技术开发有限公司,以气相色谱(GC)测定烷基糖苷组成的分析方法。以为内标,分别测定了甘油、十二醇、d-葡萄糖、丁基单糖苷及十二烷基单糖苷的相对重量校正因子,并对烷基糖苷中的诸组分进行了定量,样品测定数据表明,其相对误差在7.5%以内,变异系数不超过2...

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
