Water determination in solid and pasty samples

The gas extraction is the ideal method to detect moisture in solid and pasty substances. For this analysis, the Solid Module is combined with the Basic Module of AQUA 40.00.
The measurement of trace amounts of water is realized by the special designed heating chamber for solid and pasty samples. The sample has no contact with the reagent. Therefore the consumption of reagent is low.
The sample is applied into a sample container. So it is possible to analyse small sample amounts (down to 1 mg). The sample container is heated out in the solid chamber with temperature program or isothermal heating depending on the consistency of sample. The measurement of water content is based upon the titration according to Karl Fischer. After analysis, the used sample container is ejected from the heating chamber into collecting vessel. With closed-loop carrier gas circulation, any additional gas drying is no longer necessary: the carrier gas is continually titrated to dryness within the closed loop. The total dryness of the gas enhances the moisture desorption from the sample. Moreover, sensitive samples can be heated out very gently. Degradation’s and side reactions are eliminated. Heating with temperature program, you can distinguish
between various types of bonded water.
