分析说明
US EPA Method 610 describes the analysis of polynuclear aromatic hydrocarbons (commonly referred to as PAHs or PNAs) by both HPLC and GC. The method designates the use of a packed GC column, however capillary columns will provide better resolution, baseline stability, and longer lifetime. This application illustrates the separation of the target compound list in this method on the SLB-5ms capillary GC column. A pressure pulsed injection was used to improve response of the heavier PAHs, and to reduce .the larger vapor volume resulting from a 2 μL injection.
