Gas extraction is the ideal method for determining water content in oil samples and viscous materials. The Aquamax KF Online is perfectly suited for continuous water content analysis in oil samples.

Trace levels of water can be measured precisely using a heating chamber specifically designed for oils. Since the sample does not come into direct contact with the reagent, reagent consumption remains low while high detection sensitivity is maintained.

The oil sample is automatically withdrawn from the sampling point of the running process via a pump module and injected directly into the heating oven without contamination.

Depending on the water content, sample volumes from 0.01 mL up to 20 mL can be used. Heating can be performed either using a temperature program or isothermally.

Moisture determination takes place in the measuring cell using Karl Fischer titration. After the analysis, the oil sample can either be discharged via a valve or returned to the running process.

Closed-Loop Carrier Gas System for Maximum Efficiency

Thanks to the closed-loop carrier gas circulation, no additional gas drying is required: the carrier gas is continuously titrated to complete dryness within the system.
This ensures maximum moisture desorption from the sample while allowing gentle heating of sensitive samples, thereby minimizing degradation and side reactions.
