Aquastar ® Water Standards are the standards of choice to monitor the performance of Karl Fischer instrumentation, determine the titer of volumetric Karl Fischer reagents, and verify final water content results. These ampoulized liquid standards are directly traceable to NIST (National Institute of Standards and Technology) and are manufactured under strict control using validated procedures. MilliporeSigma is proud to introduce a novel solid standard specially designed for use in validation and control of Karl Fischer ovens and solid evaporators. It features a number of distinct advantages over other solids (e.g., lactose, citrate, and tartrate) traditionally used with KF ovens.
