Quality control of lubricants using XDS RapidLiquid Analyzer

In this application note, Metrohm demonstrates that the XDS RapidLiquid Analyzer, operating in the visible and near-infrared spectral region (Vis-NIR), promises a cost-efficient, fast alternative for the determination of the acid number of lubricants. This application note highlights NIR spectroscopy as a method that allows for rapid Acid Number analysis as no sample preparation or chemicals are needed.
