Abstract:
1. A method for validating machine performance of a mass spectrometer, comprising the steps of: a) providing a machine qualification set of samples; b) operating the mass spectrometer on the machine qualification set of samples to thereby obtain a set of performance evaluation spectra; c) executing a classification algorithm on the performance evaluation spectra with respect to a classification reference set of spectra with the aid of a programmed computer; d) executing the classification algorithm on a set of spectra obtained from the machine qualification set of samples in a previous standard machine run of the machine qualification set of samples with respect to the classification reference set with the programmed computer; e) comparing the results from the execution of the classification algorithm in step c) with the results of the execution of the classification algorithm in step d) and f) generating a machine validation result from the comparison of step e).
