✦ Synopsis

Nitrated and hydroxylated polynuclear aromatic hydrocarbons nitro-. and hydroxy-PAHs extracted from air particulates were fractionated from other micropollutants by semipreparative packed-column supercritical fluid chromatography on silicagel. Sample injection and fraction collection was automated by means of a Gilson 233 XL sample preparation station. The collected fractions were analyzed by capillary gas chromatography᎐mass spectrometry operated in the ion-monitoring mode. For some specific solutes, concentrations down to the 1 pgrm 3 level could be measured. ᮊ 1998
