CALIBRATION STANDARDS, METHODS, AND KITS FOR WATER DETERMINATION BY KARL FISCHER TITRATION

摘要

The invention relates to a formed tablet calibration standard-reagent for calibrating Karl Fischer reactions for determining water content in a substance, said reagent containing a first component, namely sodium tartrate dihydrate, and a second component, namely magnesium stearate. The invention further relates to a method for determining the water content of a substance using a Karl Fischer analysis. The invention further relates to a formed tablet calibration standard-reagent kit, comprising a sealed package containing said formed tablet calibration standard-reagent.
