Agrochemical residue analysis

The analysis of wine, juice and grapes by LC/MS/MS is accredited by the National Association of Testing Authorities (NATA) and is regularly exposed to international proficiency testing via FAPAS, BIPEA and NMI programs.

Multi-residue analysis – LC-MS/MS and GC-MS/MS

This multi-residue assay covers a broad range of fungicides and insecticides, targeting those agrochemicals which are currently registered, or recently deregistered, for viticultural use in the Australian wine industry. The analysis is available for grapes, juice and wine and uses the well-published QuEChERS extraction technique combined with the greater specificity of liquid chromatography with tandem mass spectrometry (LC-MS/MS) and gas chromatography with tandem mass spectrometry (GC-MS/MS). The LC-MS/MS assay can be performed alone or partnered with the GC-MS/MS assay to provide a greater coverage of agrochemical residues. The list of compounds determined in the LC-MS/MS assay is outlined below.
