Quality control of polyols using the XDS RapidLiquid Analyzer

This application note demonstrates how the XDS RapidLiquid Analyzer from Metrohm, operating in the visible and near-infrared spectral region (Vis-NIR) promises a cost-efficient and fast solution for the determination of the hydroxyl (OH) number of polyols. With no sample preparation or chemicals needed, Vis-NIR spectroscopy allows for the analysis of polyols in less than a minute.
