This document introduces an updated and expanded mass spectral library for analysis of pesticides and endocrine disruptors. The library contains 926 pesticides, endocrine disruptors, and related compounds, 359 more than the original library. All compounds have locked retention times that can be accurately reproduced using an Agilent GC/MS system with the ChemStation's Retention Time Locking software. The document also explains the use of Agilent's Screener software and Deconvolution Reporting Software for compound identification and screening.
Agilent Technologies has introduced an updated Pesticide and Endocrine Disruptor Database (part number G1672AA) that contains 926 entries, replacing the original RTL library. This expanded database includes all compounds specified for GC/MS analysis in the new Japanese Positive List regulations, along with metabolites, PCBs, PAHs, and fire retardants.
The document details how this database is used with Agilent's Deconvolution Reporting Software (DRS) version A.03.00 to screen GC/MS files for all 926 compounds in about two minutes per sample. The solution utilizes locked retention times and mass spectral deconvolution to identify pesticides buried in complex chromatograms by co-extracted materials.
The locked retention time for Chlorpyrifos-methyl is 16.596 min.
The user-specified time window is typically 10-20 seconds.
