ABSTRACT:
An improved technique and apparatus for automatic titration for determining the water content of a sample by a Karl Fischer (K.F.) reaction. Rather than requiring titration from one endpoint to another identical endpoint, each determination is made using a calibration relative to the water equivalent of a known amount of titrant together with the change in sensor output that occurs when a sample is added to the K.F. reagent. Improved accuracy and speed of analysis results.
