AN 50822 - Incoming Analysis of Sugars and Polysaccharides


This application note describes an experimental approach for identifying and determining the similarity of lots of glucose, lactose, sucrose, and cornstarch. The samples were run in small glass vials using the Nicolet™Antaris™ FT-NIR analyzer, a dedicated near infrared (NIR) Fourier transform infrared analyzer that covers the NIR region from 12000 cm-1 to 4000 cm-1. The calibrated method was designed to be used at multiple plant sites and was developed using calibration data collected from three separate Nicolet Antaris analyzers. Combining the data from different spectrometers to create a single calibration model allows an evaluation of spectrometer-to-spectrometer transferability of a single calibration.
