The method of determination of tetracycline antibiotics (tetracycline, chlortetracycline, oxytetracycline, doxycycline) in the milk of methods HPLC-MS/MS/MS and HPLC-QTOF-MS, with a simple and rapid sample preparation. The ranges defined concentrations of tetracyclines in milk sample of 1 g was 1–200 ?g/kg. Relative standard deviation of the results of the analysis does not exceed 7%. The analysis duration 30–40 minutes.

A method for determining the 20 pesticides (azoxystrobin, boscalid, chlorpyrifos, cyprodinil, diazinon, dimethoate, fluazifop-P-butyl, malathion, metribuzin, penconazole, phosalone, pirimicarb, piri- miphos-methyl, prometryn, propargite, pyraclostrobin, pyrimethanil, triadimenol, triadimefon, trifloxystrobin) in grapes and tomatoes by high performance liquid chromatography with tandem quadrupole – time of flight mass spectrometry detector (HPLC-MS / TOF), using sample preparation QuEChERS.
