This application note describes a method for the analysis of complex polycyclic aromatic hydrocarbons in coal tar using the Agilent J&W Select PAH column.
Coal tar is a by-product containing various organic compounds, including polycyclic aromatic hydrocarbons (PAHs). Analyzing these PAHs can be difficult due to overlapping masses in some components. This document details an optimized gas chromatography/mass spectrometry (GC/MS) method using the Agilent J&W Select PAH column.
The Select PAH column separated target PAHs in a complex mixture of coal tar in a single run with a runtime of 45 min.
PAHs with higher molecular weight were eluted at 350 °C due to the maximum programmable column temperature.
The sample concentration was approximately 0.8-21 g/mL.
