表面活性劑是人類日常生活和各行業(yè)生產(chǎn)所不能缺少的助劑,有“工業(yè)味精”的美譽(yù)。傳統(tǒng)的表面活性劑多采用石油化工原料,然而由于石油價(jià)格的上漲與資源的短缺,加之世界各國對環(huán)境問題的關(guān)注,表面活性劑工業(yè)急需開發(fā)利用天然可再生資源來生產(chǎn)易于生物降解、不污染環(huán)境且性能優(yōu)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(nèi)標(biāo),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(jìn)行了定量,樣品測定數(shù)據(jù)表明,其*大相對誤差在7%以內(nèi),變異系數(shù)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%.
