GB/T 29672-2013 化妆品中丙xi腈的测定 气相色谱-质谱法

本标准规定了化妆品中丙xi腈的气相色谱-质谱测定方法。

本标准适用于膏霜、水剂、散粉、香波、唇膏类化妆品中丙xi腈的测定。

本标准对于丙xi腈的检出限为0.2mg/kg，定量限为0.4mg/kg。

浩瀚色谱（山东）应用技术开发有限公司研发一种气相色谱-质谱法测定化妆品中的丙烯腈的方法，包括如下步骤：向待测样品中加入甲醇，超声提取，提取液离心，取上清液，氮气吹干，10％甲醇水溶液溶解，然后用亲水亲脂固相萃取柱净化，体积百分比80％甲醇水溶液洗脱亲水亲脂固相萃取柱，得到的洗脱液进行脱水，浓缩，滤膜过滤，进行气相色谱-质谱测定；气相色谱的色谱柱为键合/交联聚乙醇固定相的色谱柱，规格为60m×0.25mm×0.50μm；色谱柱采用程序升温：60℃保持3min，然后4℃/min升温100℃保持2min，再以20℃/min升温220℃；分流进样，分流比为10∶1。气相色谱-质谱法测定化妆品中的丙烯腈的方法快速、检测限低、回收率高。

Determination of Acrylonitrile in Cosmetics by Capillary Column
Determination of Acrylonitrile in Cosmetics by Capillary Column Details:

Name: Capillary Column

Stationary phase: polyethylene glycol

Specification: 30m*0.25mm*0.25um

Model: HH-INNOWAX

Application: GB/T 29672-2013 Determination of Propionitrile in Cosmetics Gas Chromatography-Mass Spectrometry

GB/T 29672-2013 Determination of Propanonitrile in Cosmetics Gas Chromatography-Mass Spectrometry

This standard specifies the gas chromatography-mass spectrometry method for the determination of propionitrile in cosmetics.

This standard applies to the determination of acetonitrile in creams, liquids, powders, shampoos, and lipstick cosmetics.

The detection limit of this standard for propionitrile is 0.2mg/kg, and the limit of quantification is 0.4mg/kg.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. has developed a gas chromatography-mass spectrometry method for the determination of acrylonitrile in cosmetics, including the following steps: adding methanol to the sample to be tested, ultrasonic extraction, centrifugation of the extract, and taking the supernatant , Dried with nitrogen, dissolved in 10% methanol aqueous solution, and then purified with a hydrophilic lipophilic solid phase extraction column, and the volume percentage 80% methanol aqueous solution was used to elute the hydrophilic lipophilic solid phase extraction column. The obtained eluate was dehydrated and concentrated. Filter by membrane and perform gas chromatography-mass spectrometry; the chromatographic column of gas chromatograph is a column of bonded/crosslinked polyethanol stationary phase, the specification is 60m×0.25mm×0.50μm; the chromatographic column adopts temperature program: 60℃ for 3min , Then the temperature is raised to 100°C at 4°C/min for 2 minutes, and then the temperature is raised to 220°C at 20°C/min; the sample is split and the split ratio is 10:1. The gas chromatography-mass spectrometry method for the determination of acrylonitrile in cosmetics is fast, with low detection limit and high recovery rate.
