Abstract
Surfactants plays an important role in reducing surface tension, as it enables the control interfacial tension between liquids or solid-liquids. The application has been increasing world wide and safety concern regarding the long term exposure to surfactant has been long discussed. Hence, the identification of surfactants in final products are crucial. The new method has been develop in headspace gas chromatography – selected ion monitoring mode (HS-GCMS-SIM mode) allowed the collection of surfactants as SIM-Fingerprint-ID. The advantage of the method is it applies to a broad range surfactants containing different chemistries. In addition, the analyses incorporate green chromatographic technique which reduces environmental impact/pollution with simple sample preparations. This database allows direct identification of the types of surfactants without derivatization, fast analysis time and ability of low concentration tracing.
