This application note describes a fast method for analyzing polycyclic aromatic hydrocarbons (PAHs) in coal tar using an optimized oven program and an Agilent J&W Select PAH column.
The document details a method for analyzing complex mixtures of polycyclic aromatic hydrocarbons (PAHs) found in coal tar. It addresses the difficulty of separating PAHs with similar masses by utilizing specific column selectivity and an optimized temperature program.
The analysis was performed using Gas Chromatography/Mass Spectrometry (GC/MS) with a Triple Quad detector. The method utilizes the Agilent J&W Select PAH column (15 m x 0.15 mm, df= 0.10 ym), demonstrating its ability to separate regulated PAH isomers in a single run within approximately 29 minutes.
| Column Length | 15 m |
|---|---|
| Column Inner Diameter | 0.15 mm |
| Film Thickness | 0.10 ym |
| Part Number | CP7461 |
| Run Time | 29 min |
The part number for the Select PAH column is CP7461.
The analysis of target PAHs in a complex mixture takes 29 minutes.
A Triple Quad detector operating in Elin FS or SIM mode is used.
