This application note describes the use of a fully automated on-line LC-GC system for the clean-up and determination of PAH in urban air particulate extracts. The system consists of a high-performance liquid chromatograph (LC) coupled on-line to a gas chromatograph (GC).
The document details the construction and operation of an automated analytical system coupling High Performance Liquid Chromatography (LC) with Gas Chromatography (GC). The system is designed for the analysis of Polycyclic Aromatic Hydrocarbons (PAH) found in urban air particulate extracts. It utilizes a Varian 9001 LC pump and a Varian 3700 GC to achieve high sensitivity and automation.
The detection limit was determined to be approximately 1 ng per sample at a signal-to-noise ratio of 3:1.
Pentane was selected as the LC mobile phase.
