Acceptability criteria for linear dependence in validating UV-spectrophotometric methods of quantitative determination in forensic and toxicological analysis
Published 2014-08-01“…The next criteria and the order of acceptability estimation of linearity for UV-spectrophotometric methods of quantitative determination analyses in biological fluids used in forensic and toxicological analysis have been offered: acceptability estimation of linear dependence parameters is carried out in two stages – for the lines obtained using model solutions (without matrix) and calibration samples respectively; two approaches has been suggested for parameters estimation of linear dependence obtained using model solutions; they are based on: 1) assumption of equality of the uncertainty related to the procedure of sample preparation of calibration standards, and the uncertainty of the calibration curve plotted by model solutions; 2) assumption of insignificance of the uncertainty of the calibration curve plotted by model solutions; for both approaches the acceptability criteria have been offered for residual standard deviation and correlation coefficient ; for estimation of parameters of linear dependence obtained using calibration samples it has been suggested to proceed from assumption of equality of the calibration uncertainty and the uncertainty of measuring the absorbance and sample preparation of the sample to be analysed; within this approach the acceptability criteria have been offered for residual standard deviation RSD0 and correlation coefficient Rс; the parameters of within-run (within-day) and between-run (between-day) linearity should satisfy these criteria. …”
