Prozentuales und logarithmisches Verfahren zur Berechnung von Eichkurven

Two methods, one on the basis of percent and another on the basis of logarithm, for the calculation of calibration curves are reported. By these procedures the lower values of the calibration curves are represented more strongly than by the normal method of the least sum of error squares. Instead of the coefficient of correlation a coefficient of quality is defined, to characterize the quality of the calibration curves. The coefficient of quality is calculated from the percentage deviations of the calculated x-values in the way of the standard deviation.
