摘要：

A new method to obtain the signal associated with a chromatographic blank is presented for inclusion within calibration procedures, Signal assigned to the blank is obtained by direct integration of the background noise by using extrapolated values of the base-peak width at concentrations different to the 'zero concentration'. Thus, detection limits which are better adjusted to a statistical evaluation are implemented. These limits are more in line with IUPAC recommendations.
