Agilent 5890 Series II Optimized Analysis of Gasoline BTEX in Water Soil Using GC/FID with Purge Trap Application Note
This document describes an optimized method for determining gasoline components, specifically gasoline range organics (GROs) and benzene, toluene, ethylbenzene, and xylenes (BTEX), in contaminated water and soil. The method utilizes modified EPA Methods 8015/8020 with capillary gas chromatography (GC) and a flame ionization detector (FID) or photoionization detector (PID). The analysis employs an Agilent 7695A Purge and Trap (P and T) system coupled with an Agilent 5890 Series II gas chromatograph.

Questions answered in these manuals
What is the optimal sample purge time for gasoline and GROs analysis?
The optimal sample purge time is 11 minutes, or 440 ml of helium purge gas, to ensure efficient recovery of high-boiling fractions.
What is the optimal GC run time achieved in this study?
The optimized GC run time achieved is 17 minutes using a thin-film HP-1 column and faster oven temperature programs.
What instruments is this bracket kit compatible with?
The document assumes the Gas Chromatograph (GC) is either a 5890A GC fully upgraded to a 5890 Series II instrument or a 5890 Series II GC purchased as such.
