It does not require time-consuming sample preparation: Weigh the sample in a headspace vial, close and seal the vial, and then administer it into the AQUA 40.00 headspace oven.

The analysis procedure starts with heating up the sample up to a temperature set prior. A carrier gas transports the moisture from the sample into the measuring cell where the moisture is titrated.

With the unique advantage of the system using the closed-loop-carrier gas circulation, any additional gas drying is no longer necessary. Hence, the carrier gas is continually titrated to dryness within the closed loop.

The total dryness of the gas enhances the moisture liberation, and sensitive samples can be heated out very gently. Moisture liberation becomes possible even at ambient temperature.

All these advantages result in reducing reagent consumption considerably. Furthermore, temperature-programmed heating procedure can be defined individually by the user. Such a temperature program reveals in which way the moisture in question is bonded to the sample substance. You can distinguish between chemically bonded water of crystallization and adsorbed surface water.
