Abstract
Nitrated and hydroxylated polynuclear aromatic hydrocarbons (nitro- an d hydroxy-PAHs) extracted from air particulates were fractionated from other micropollutants by semipreparative packed-column supercritical fluid chromatography on silicagel. Sample injection and fraction colle ction was automated by means of a Gilson 233 XL sample preparation sta tion. The collected fractions were analyzed by capillary gas chromatog raphy-mass spectrometry operated in the ion-monitoring mode. For some specific solutes, concentrations down to the 1 pg/m(3) level could be measured. (C) 1998 John Wiley & Sons, Inc.
