This article describes a GC/MS system for the rapid screening of foodstuffs for chemical contaminants with a special emphasis on pesticides, organophosphorus, and organosulfur compounds.
This document details a Gas Chromatography/Mass Spectrometry (GC/MS) system designed for the rapid screening of foodstuffs for chemical contaminants, specifically pesticides, organophosphorus, and organosulfur compounds. The system utilizes a 6890N GC with a 5973N Inert MSD and a dual-wavelength flame photometric detector (DFPD) to achieve analysis times three times faster than conventional methods.
| Total run time | 13.96 min |
|---|---|
| Column Length | 15.0m |
| Column Diameter | 0.25 mm |
| Inlet Temperature | 250 °C |
| Split ratio | 10:1 |
Analysis times can be shortened by at least three-fold versus conventional methods.
The Agilent Deconvolution Reporting Software (DRS) is used, which utilizes the AMDIS deconvolution program from NIST.
