表面活性劑是人類日常生活和各行業生產所不能缺少的助劑,有“工業味精”的美譽。傳統的表面活性劑多采用石油化工原料,然而由于石油價格的上漲與資源的短缺,加之世界各國對環境問題的關注,表面活性劑工業急需開發利用天然可再生資源來生產易于生物降解、不污染環境且性能優良的表面活性劑。
浩瀚色譜采用氣相色譜(GC)測定烷基糖苷組成的分析方法。以正廿二烷為內標,分別測定了甘油、十二醇、d-葡萄糖、丁基單糖苷及十二烷基單糖苷的相對重量校正因子,并對烷基糖苷中的諸組分進行了定量,樣品測定數據表明,其*大相對誤差在7%以內,變異系數不超過2%。

Surfactants are indispensable additives in human daily life and production in various industries, earning the reputation of "industrial monosodium glutamate". The traditional surfactant mostly uses petrochemical raw materials. However, due to the rising price of petroleum and the shortage of resources, as well as the concern of countries around the world about environmental issues, the surfactant industry urgently needs to develop and utilize natural Renewable resource to produce surfactants that are easy to be biodegradable, do not pollute the environment, and have excellent performance.
Haohan Chromatography uses gas chromatography (GC) to determine the composition of alkyl glycosides. The relative weight correction factors of glycerol, dodecanol, d-glucose, butyl monoglycoside, and dodecyl monoglycoside were determined using n-dodecane as the internal standard, and the various components in alkyl glycoside were quantified. The sample measurement data showed that the relative error was within 7%, and the coefficient of variation was not more than 2%.
