The gas extraction is the ideal method to detect moisture in oil samples and viscous substances. For this analysis, the Oil Module is combined with the Basic Module of AQUA 40.00.
Trace amounts of water can be measured with the special heating chamber for oils. The sample has no contact with the reagent. Therefore the consumption of reagent is low.
Using an appropriate syringe, oil sample is injected through the septum into heating oven without a contamination of device. It is possible to apply sample volumes from 0.01 up to
20 mL depending on water content.
The sample can be heated out with temperature program or isothermal heating. The measurement is carried out in the measuring cell with titration method according to Karl Fischer. After analysis, the used oil sample flows out through a valve.
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. Degradations and side reactions are eliminated.
You can distinguish between various types of bonded water when you use heating with temperature program.
