Procedure for processing measuring data and device to perform the process

Abstract

The invention concerns a procedure for processing measuring data and a device to perform the procedure, wherein the measuring data can be determined by using a measurement system, more particularly a chromatographic analyzing system, for the measurement of measuring values that correspond to certain useful information about, or of, a technical process and that depend on at least two variables. In the procedure, the following measures are taken: e) Performing a calibration step, including: a1) Stimulation of the measuring system by changing cause variables responsible for systematic measuring errors and determining the corresponding measuring data, using the measurement system; a2) Determination of effect vectors corresponding to systematic measuring errors from the measuring data obtained in step a1) by using a mathematical procedure, more particularly a factor analysis, wherein the effect vectors that correspond to the measuring errors are based on a mathematical model with which the measuring data can be estimated at least in approximation and wherein the model contains at least one error term containing an effect vector assigned to an measuring error and a corresponding error value; f) Performing a measuring step, including: b1) Determining measuring data corresponding to certain useful information about, or of, the technical process while the technical process is taking place; b2) Reducing the measuring data gathered in step b1) to linear components, based on the effect vectors determined in step a2) that correspond to the measuring errors, by using a mathematical procedure, more particularly a linear regression procedure, in order to determine the error contributions with which useful information, which are been corrected for systematical measuring errors, can be determined.
