Statistische Auswertung der massenspektrometrischen Gruppenanalyse von Benzinen

A possibility has been found to carry out corrections on the mass spectrometric determination of the hydrocarbon groups in non-olefinic petrols on the basis of the measurements of a single test mixture with sufficient accuracy. A simple method is described for the elimination of the systematic errors in petrol analyses carried out with other instruments than those employed for the calibration factors. The results have also confirmed the conclusions of Benz that with such a method in different laboratories no extensive calibrations are required.
