Agilent Technologies triple quadruple GC/MS pesticide analysers

Agilent Technologies has introduced two triple quadruple GC/MS pesticide analysers. They are complete, factory-configured, highly sensitive and chemically tested systems that can identify a range of commonly analysed pesticide residues.

The analysers are based on the 7000 series triple quadruple gas chromatograph/mass spectrometer. The series is specifically for GC analysis, providing the levels of sensitivity and selectivity needed to measure trace levels in complex matrices.

Multiple reaction monitoring allows for reduction or elimination of matrix interferences that restrict the accuracy or detection limits of other techniques. The pesticide analysers come with an MRM database containing a broad range of commonly tested pesticides.

The first version of the analyser is designed for maximum flexibility, permitting users to add GC detectors. It is easily scaled to shorten run times and includes a method based on a retention time locked GC/MS/MS MRM database containing spectra for more than 500 pesticides.

The second version has good performance and shorter cycle times while consuming less carrier gas. It is based on the US targeted pesticide list GC/MS/MS MRM database of more than 200 pesticides.

Included with each analyser are a full set of pesticide checkout samples, a promotional ‘quick, easy, cheap, effective, rugged and safe’ sample preparation kit and a retention time locked HP-5MS ultra inert column for reliable database matching. There is also a quick-start guide and application note that shows users how to run the analyser’s screening method, and a CD-ROM with examples of screening methods, data files and reports.

The analysers are configured with capillary flow technology, enabling rugged, reliable GC column backflush, which can shorten run times, extend column life, reduce chemical background noise, provide consistent retention times and spectra, and keep the MS ionisation source clean.
