Agilent 6890Plus/5973N Nitrofen Determination Application Note
This document describes an analytical method for determining the herbicide Nitrofen in turkey meat using Gas Chromatography/Mass Spectrometry (GC/MS). The application focuses on the advantages of Negative Chemical Ionization (NCI) mode over Electron Impact (EI) mode for detecting analytes with high electron affinity in complex food matrices.
The text details the experimental setup, including the use of Agilent 6890Plus and 5973N MSD instruments with EPC modules and Retention Time Locking (RTL). It outlines the sample preparation procedure according to DFGS 19 and presents results comparing EI and NCI detection modes, highlighting the superior sensitivity and selectivity of NCI for Nitrofen detection. This manual is written in German.
