Abstract

The invention discloses a multivariable analysis method based on angle measurement, and relates to a method for noncontact analysis on products. The method comprises the following steps: measuring a measured sample and a measured component to obtain the multipoint strength measurement value of the measured sample and the measured component; converting the multipoint strength measurement value of the measured sample and the measured component into an angle metric of the measured sample and the measured component; selecting a modeling sample; converting the multipoint strength measurement value of the measured sample and the measured component into the angle metric of the modeling sample and the measured component; building a multivariable regression model by taking the measured component content of the modeling sample as a dependent variable and the angle metric of the modeling sample and the measured component as an independent variable; and substituting the angle metric of the measured sample and the measured component into the multivariable regression model to predict the content of the measured component in the whole hybrid system. According to the multivariable analysis method, requirement on the environment in the analysis operation is obviously lowered, complexity of instrument can be reduced, and the multivariable analysis method is suitable for chemical analysis, process analysis and instrument analysis.

Description

Technical field

[0001] The present invention involves a method used to conduct non -contact analysis of the product, especially a multi -variable analysis method that applies the multiple component system system. Background technique

[0002] Process analysis technology divides the development of measurement methods into five stages: OFF-LINE (offline analysis), AT-LINE (near line analysis), on-line) And NoninVasive, in which on-line is divided into intermittents and Continuous.The IN-LINE stage refers to the fact that the measured material cannot be removed and pre-processed. Non-contact analysis is more difficult to handle and operate the measured object during measurement. It is even more commonly analyzed that the required heavy-duty analysis environment may be difficult to meetTherefore, these stages have made very high requirements for analysis methods.The usual analysis is very strict with the reappearance of the environment. Taking the light analysis as an example, its qu...
