DESCRIPTION
BS ISO 19619:2018
This standard BS ISO 19619:2018 Surface active agents. Determination of free propylene oxide content in propylene oxide adduct surfactants. GC method is classified in these ICS categories:
- 71.100.40 Surface active agents
This document specifies an analytical procedure for the determination of free propylene oxide in surfactants which are synthesized from propylene oxide copolymers.
The method is appropriate for the qualitative and quantitative determination of propylene oxide groups in propylene oxide adducts, polyethers and polyglycol esters by headspace gas chromatography (HS-GC) with a flame ionization detector (FID) based on external procedure. Gas chromatography-mass spectrometry (GC-MS) is used for the confirmatory purposes.
