    Precision Limits and Interval Estimation in the Calibration of 1-hydroxypyrene in Urine and Hexachlorbenzene in Water, Applying theRegression Triplet Procedure on Chromatographic Data

  • Original language description

    A method for the determination of 1-hydroxypyrene in urine and hexychlorbenzene in water applying the regression triplet in the calibration procedure of chromatographic data has been applied using the program QCEXPERT. The detection limit and quantification limit are currently calculated on the basis of the standard deviation of replicate analyses at a single concentration. However, since the standard deviation depends on concentration, these single concentration techniques result in limits that are directly dependent on spiking concentration. A more rigorous approach requires at first careful attention to the three components of the regression triplet (data, model, method), examining (a) the data quality of the proposed model; (b) the model quality; (c) the LS method to be used for a fulfilment of all least squares assumptions. On HPLC determination of 1-hydroxypyrene in urine and gas chromatography analysis of hexachlorbenzene in water, this paper describes the effects of deviations

    Limity přesnosti a intervalové odhady v kalibraci 1-hydroxypyrenu v moči a hexachlorbenzenu ve vodě aplikací regresního tripletu na chromatografická data

  • Czech description

    Limity přesnosti a intervalové odhady při kalibraci 1-hydroxypyrenu v moči a hexachlorbenzenu ve vodě aplikací regresního tripletu na chromatografická data byly provedeny programem QCEXPERT. Limita detekce a limita kvantifikace spolu s kritickou urovní byly vyhodnoceny na základě opakovaných meření v kalibračním grafu. Kalibrační graf byl analyzován lineární regresí s využitím regresního tripletu (kritika dat, kritika modelu a kritika metody). Ukázalo se, že odlehlé hodnoty kalibračního grafu silně ovlivňují limitu detekce a intervalový odhad neznámé koncentrace ve vzorku a je třeba jim proto věnovat pozornost.
