Ga. Mackay et Rm. Smith, SUPERCRITICAL-FLUID EXTRACTION AND CHROMATOGRAPHY MASS-SPECTROMETRY OF FLAME RETARDANTS FROM POLYURETHANE FOAMS, Analyst, 118(7), 1993, pp. 741-745
Four chlorinated organophosphate flame retardants present in polyureth
ane foams were analysed by supercritical fluid chromatography with fla
me-ionization detection and mass spectrometry. In addition, their amen
ability to gas chromatography was investigated. Real samples were anal
ysed by using these techniques after on-line extraction with supercrit
ical carbon dioxide. On-line quantitative extraction of the flame reta
rdants from the polyurethane foams was investigated by using an extern
al calibration.
