Rapid analysis of pesticides in vegetables by Agilent 5975T LTM GC/MSD and TSP
The document details an evaluation of the Agilent 5975T LTM GC/MSD for detecting pesticides in vegetable extracts without requiring a traditional clean-up step. It utilizes the Thermal Separation Probe (TSP) technology to minimize sample preparation time while maintaining quantitative and confirmatory results.
The study establishes a fast method using DRS software and RTL functions, achieving blind added multi-pesticide confirmation within 2-3 minutes. The application covers organo-phosphorous, organo-chlorine, and pyrethroid pesticides in samples such as cucumbers, tomatoes, and green peppers.
The procedure requires placing a small amount of sample material or liquid extract into a 40 pL disposable micro-vial.
The test evaluated organo-chloro pesticide solutions at a concentration of 1.0 pg/mL.
The system was tested with 50 continuous injections of tomato extractions without a clean-up step.
