Coulometric KF with 1 % Oven Water Standard
Automated titration method for samples with low water content
In this application 1% oven water standard was used to check the system suitability of coulometric Karl Fischer titrator connected to an InMotion KF Pro titration autosampler.
Background
The combination of the oven technique with coulometric Karl Fischer titration is ideal for samples with low water content. With the InMotion KF oven autosampler, plastics, petroleum products, inorganic raw materials as well as some food products (grains, starchy food) can be analyzed fully automated.
The system Coulometer-KF with the InMotion KF oven autosampler is checked using a solid 1 % oven water standard. The recommended water gas phase extraction temperature is 170 °C. Water is evaporated in the InMotion KF oven autosampler and transferred into the titration cell where it is determined by coulometric KF analysis on a C30S. For the same application, also the Excellence line titrators T7 or T9 can be used.
