When measuring moisture with a Karl Fischer analyzer, most samples can be added directly to the generator cell/titration cell for simple, accurate testing. Some samples, however, cannot be added directly because their moisture is not released naturally or they undergo side reactions with the Karl Fischer reagent — for example powders, granules, pastes, and oxidizing inorganic salts.

For samples that cannot be added directly to the cell, pairing the WKT-V2 Karl Fischer oven for gas-phase extraction is the perfect solution. The sample is placed in a vial and moved onto the oven, heated to a specific temperature (up to 300˚C), and the moisture is extracted and carried into the cell by dry air or nitrogen, then measured perfectly.
