The MS/MS analysis efficiently ejects all but the ion of interest out of the trap, eliminates the matrix from the quantitation of the target compounds, and provides unequivocal confirmation
Thermo Electron has developed new GC/MS applications for the accurate analysis of pesticides and PCB residues using the Finnigan PolarisQ and the Finnigan Trace DSQ benchtop GC/MS mass spectrometers.
Designed to rapidly and accurately detect and analyse low level analytes, these applications are particularly suited to environmental laboratories and government agencies helping them to maximise productivity and profitability.
The analysis of pesticide and PCB residues presents significant analytical challenges.
Considerable pressure for lower detection limits of these compounds prompts laboratories to seek methods that enable them to reproducibly attain results in the pg/ul range.
The Finnigan PolarisQ uses the tandem mass spectrometry method to remove the matrix ions from the mass spectrum.
This method eliminates false positives and elevated concentration values from matrix interferences that can be present in other analysis methods.
The MS/MS analysis efficiently ejects all but the ion of interest out of the trap, eliminates the matrix from the quantitation of the target compounds, and provides unequivocal confirmation.
The Finnigan Trace DSQ combines a large volume splitless injection with full scan gas chromatography/mass spectrometry to accomplish low level analysis with decreased sample preparation time.
This application offers increased confidence in compound identification in routine and complex pesticide analysis.
