Supercritical fluid extraction and chromatography—mass spectrometry of flame retardants from polyurethane foams

Abstract

Four chlorinated organophosphate flame retardants present in polyurethane foams were analysed by supercritical fluid chromatography with flame-ionization detection and mass spectrometry. In addition, their amenability to gas chromatography was investigated. Real samples were analysed by using these techniques after on-line extraction with supercritical carbon dioxide. On-line quantitative extraction of the flame retardants from the polyurethane foams was investigated by using an external calibration.
