20.500.12556/DKUM-21855 DOLOČANJE OSTANKOV PESTICIDOV V VZORCIH ŽITARIC S PLINSKO KROMATOGRAFIJO IN MASNO SPEKTROMETRIJO DETERMINATION OF PESTICIDE RESIDUES IN CEREALS WITH GAS CHROMATOGRAPHY AND MASS SPECTROMETRY Namen diplomske naloge je bil določiti ostanke pesticidov v vzorcih žitaric in izdelkih iz žit. Za določitev ostankov pesticidov v vzorcih žitaric smo uporabili metodo plinske kromatografije z masno selektivnim detektorjem (GC/MS) in metodo izbranih ionov (SIM – selected ion monitoring). Za kvantitativno določitev z GC/MS smo uporabili interne standarde alfa-HCH-D6 in fenantren-D10. Rezultate vsebnosti ostankov pesticidov smo ovrednotili glede na zahteve analizne metode (linearnost, ponovljivost, obnovljivost, točnost, meja določjivosti – LOQ, meja zaznavnosti – LOD, selektivnost). The aim of diploma thesis is determination of pesticide residues in cereals and products of cereal. Gas chromatography with mass spectrometry (GC/MS) was used for determination of pesticide residues. Phenantrene –D10 and alpha-HCH-D6 were used as internal standards for quantitation purposes. Results were statistically evaluated according to validation requirements (linearity, repeatability, accuracy, reproducibility, limit of quantitation, limit of detection, selectivity). pesticidi žitarice plinska kromatografija z masno selektivnim detektorjem validacija pesticides cereals gas chromatography with mass spectrometry validation of analytical method true true false [I.
