ABSTRACT:
The invention relates to a formed tablet calibration standard-reagent for calibrating Karl Fischer reactions for determining water content in a substance, the 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 that includes a sealed package containing a formed tablet calibration standard-reagent for a Karl Fischer reaction.
