ESTIMATE OF GAS-CHROMATOGRAPHIC BLANKS - APPLICATION TO DETECTION LIMITS EVALUATION AS RECOMMENDED BY IUPAC

A new method to obtain the signal associated with a chromatographic bl ank is presented for inclusion within calibration procedures, Signal a ssigned to the blank is obtained by direct integration of the backgrou nd noise by using extrapolated values of the base-peak width at concen trations 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.
