Determination of Acrylo
nitrile in Cosmetics by Capillary Column Details:
Name: Capillary Column
Statio
nary phase: polyethylene glycol
Specification: 30m*0.25mm*0.25um
Model: HH-INNOWAX
Application: GB/T 29672-2013 Determination of Propio
nitrile in Cosmetics Gas Chromatography-Mass Spectrometry
GB/T 29672-2013 Determination of Propano
nitrile in Cosmetics Gas Chromatography-Mass Spectrometry
This standard specifies the gas chromatography-mass spectrometry method for the determination of propio
nitrile in cosmetics.
This standard applies to the determination of aceto
nitrile in creams, liquids, powders, shampoos, and lipstick cosmetics.
The detection limit of this standard for propio
nitrile 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 acrylo
nitrile in cosmetics, including the following steps: adding methanol to the sample to be tested, ultraso
nic 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/crossl
inked polyethanol statio
nary 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 acrylo
nitrile in cosmetics is fast, with low detection limit and high recovery rate.
