The water determination in solid and pasty samples, oils and viscous compounds is very easy with the Karl Fischer Titrator AQUA 40.00 with Vario Head Space Module.
No sample preparation is required: Weigh the sample in a headspace vial, close and seal the vial, and then start the analysis.
The closed loop carrier gas circulation is the unique advantage of the system. No additional gas drying is necessary. The carrier gas titrates dry continually within the closed loop. The total dryness of the gas supports the moisture release. This is important to heat sensitive samples gently. These advantages result in reducing reagent consumption considerably.
The manual version of Vario Head Space Module can be easily extended to the fully automated version with auto sampler (for vial sizes 2 R to 50 R). The modification for other sample vials is quickly and comfortably – just by changing the oven unit and the sample rack - with automatic ID and storage of all adjustments in defaults.
