This quality control material is specifically for a range of pesticide residues that are generally determined using specific single-residue methods. Most pesticide residues are determined using multi-residue methods, that is ones in which potentially hundreds of compounds can be measured with a single extraction protocol and instrumental method, based on multi-stage mass spectrometry. However, some pesticides are not very amenable to the generic multi-residue approach and still require more specific extraction regimes and chromatographic-mass spectrometric approaches.
Chlormequat, mepiquat and trinexapac-ethyl are plant growth regulators, with glyphosate being a broad‑spectrum systemic herbicide used routinely across the world. Glyphosate is of key interest to the market at the moment, as the regulators decide how to proceed with the use of the herbicide and whether it should be banned. The residue definition to include its principal degradation products and metabolites, especially AMPA, means that methods are now being extended to include these related compounds. Testing proficiency is therefore needed to take advantage of this potential regulation change, where a large section of the global food supply chain would be affected.
Quality control materials can be effective in tracking improvements in testing ability, and standardising testing practices through staff training measures. Quality control materials can be used as an effective tool for method verification, to ensure standardised and repeatable results across a range of testing environments.
