Abstract
A method for processing measuring data and a device to perform the method, 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 information about, or of, a technical process and that depend on at least two variables.
Claims19
A method for processing measuring data from a measuring system, wherein the method comprises:
- a) calibrating the measuring system, wherein said calibrating includes:
- a1) stimulating the measuring system by changing cause variables responsible for systematic measuring errors of the measuring system, and determining corresponding measuring data;
- and
- a2) determining effect vectors corresponding to systematic measuring errors from the measuring data obtained in step a1) by using a mathematical method, wherein the effect vectors are based on a mathematical model with which the measuring data is estimated, wherein the mathematical model contains an error term containing an effect vector assigned to a measuring error and a corresponding error contribution;
- b) measuring, using the measuring system, wherein said measuring includes:
- b1) obtaining measuring data that corresponds to information concerning a process, while the process is taking place, and that depends on at least two variables;
- and
- b2) transforming the measuring data gathered in step b1) to linear components, based on the effect vectors determined in step a2),
- b3) using a mathematical method that corrects said transformed measuring data from step b2) for said systematic measuring errors;
- and
- b4) outputting the corrected transformed measuring data from step b3.
