A U.S. Patent Application for a ” Method and Apparatus for Quantifying Solutions Comprised of Multiple Analytes”  was published by Finesse on April 25th, 2019. The present invention is a multi-analyte sensor system based on hollow core photonic bandgap fiber and Raman anti-Stokes spectroscopy. The system includes: i) an inlet to introduce an analyte sample into an analyzer chamber which analyzer includes; ii) a measurement system to derive the anti-Stokes spectral peaks and/or spectra of the sample; iii) a set of reference calibrants corresponding to the analytes of which the sample is primarily comprised; iv) a second inlet to introduce said calibrants into the analyzer. Learn More
