MONITORING OIL CONDITION AND/OR QUALITY, ON-LINE OR AT-LINE, BASED ON CHEMOMETRIC DATA ANALYSIS OF FLOURESCENCE AND/OR NEAR INFRARED SPECTRA

摘要

The present invention relates to a method and a device for monitoring oil condition and/or quality based on fluorescence and/or NIR spectra as well as laboratory reference measurements on a set of oil samples. Through the use of chemometric data analysis (i.e. multivariate data analysis) the spectroscopic signals and patterns will be correlated to the laboratory reference measurements that describe the condition and/or quality of the oil. Based on this relation it is possible to predict the reference measurements and/or conditions of a new oil sample based solely on a fluorescence and/or NIR spectrum of the sample.
