Analysis of pesticide residues

For the purpose of testing the health safety of food and animal feed, our laboratory conducts testing of pesticide residues by the multiresidual method and quantifies more than 400 active substances of pesticides.

The multiresidual method  is based on multiple mass spectrometry related to liquid and gas chromatography (LC-MS / MS and GC-MS/MS) which determines different chemical groups of pesticides - (organophosphorus, organochlorine, triazine, strobilurin, nicotine, carbamates and avermectins etc.) which also have different purposes (insecticides, fungicides, acaricides, herbicides, limacides, etc).

Fungicides from the group of dithiocarbamates  (propineb, thiram, ciram, mancozeb, metiram)  are determined as a CS2 technique of gas chromatography with a sampler for volatile samples (headspace autosampler) and an electron capture detector (HSS-GC-ECD).  

Polar pesticides  (glyphosate, chlormequat, mepiquat) and their metabolites are determined by the method recommended by the EU Reference Laboratory (QuPPe method), LC-MS/MS technique .   

Copper compounds are  determined as copper by atomic absorption spectrometry (AAS).

Pesticide residues from the group of phenoxycarboxylic acids (clodinafop, haloxyfop, fluazifop and kizalofop) are determined by the method of which hydrolysis is an integral part. Analysis of pesticide residues without hydrolysis cannot meet the requirements of Regulation (EC) no. 396/2005 on maximum levels of pesticide residues in or on food and feed of plant and animal origin, which prescribe the definitions of pesticide residues.  

Analytical methods are accredited and fully meet the requirements of legal regulations, primarily EU Regulation 396/2005. 

Through the project IPA2007 / HR / 16IPO / 001-040401 - "Quality control and health safety of the food we eat", our laboratory has improved the possibility of pesticide analysis by purchasing the instrument GC-MS/MS.
