The AQUA 40.00 Vario combines the Karl Fischer Titration with the headspace technique. This offers a wide range of interesting applications to determine moisture in solid and pasty samples, oils and viscous compounds.

The sample preparation takes place using the dynamic headspace technique. The sample – in a closed vial – is placed into the headspace oven and tempered.

A closed-loop gas circulation with dry carrier gas flows across the sample and transports the extracted water completely into the measuring cell, where the analysis is carried out by titration according to the Karl Fischer method.
