First Claim
Patent Images
1. A method of assessing at least one characteristic of a fluid held in an original container utilizing visible-near infrared (VIS-NIR) spectroscopy, the method comprising:
- subjecting at least a part of the fluid in the container to VIS-NIR electromagnetic radiation;
obtaining at least a part of the VIS-NIR transflectance spectra of the fluid; and
correlating at least a part of the spectra obtained with a reference data set utilizing chemometric analysis to assess at least one characteristic of the fluid.

Abstract
A method is described for assessing at least one characteristic of a fluid held in a container that utilizes visible—near infrared (VIS-NIR) spectroscopy in combination with chemometrics. A method is also provided for calibrating VIS-NIR analyser(s) operating in transflectance mode for one or more characteristics of a fluid.
