The document describes the ability to identify and quantify compounds based on single and dual column analyses. Instruments used include Agilent Technologies 6890 with other Hewlett-Packard instruments and data systems. The document demonstrates the acquisition and analysis of combined GC/MSD and GC/FID data.
This document describes a method for combining data from a Gas Chromatograph/Mass Spectrometer Detector (GC/MSD) and a Gas Chromatograph/Flame Ionization Detector (GC/FID) to increase the information available from analyses. The combined data allows for identification via mass spectra and quantitation via the GC detector, offering benefits such as faster method development and maximum information extraction. The note focuses on configurations using the Agilent 6890 Series GC and 5972 MSD controlled by the Productivity ChemStation.
| Carrier Gas | Helium |
|---|---|
| Column Type | 30 m × 0.25 mm ID HP-5MS fused silica |
| Column Flow | 1.5 mL/min |
| Operating System | MS Windows 95 |
| ChemStation Version | Productivity ChemStation (revision A.03.00) |
The combined data provides identification with mass spectra, quantitation by the GC detector, faster method development, and maximum information from each analysis.
The recommended configuration uses a single injection port and injector with the sample separated on a single column and split post-column to the two detectors.
A tool in the data analysis software allows the GC signal to be time aligned with the MS signal based on a two point linear fit.
