Online determination of water content in oil samples

The gas extraction is the ideal method to detect water content in oil samples and viscous substances. For this analysis, the Oil Module is combined with the Basic Module of AQUA 40.00 and the Pump Module.

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 and the detection sensitivity is high.

The oil sample is transferred automatically from sampling point of running process by using the pump module. The sample is injected into heating oven without any contamination. Oil sample volumes can be used in a range 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 or returns to the running process.

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 water desorption from the sample. Moreover, sensitive samples can be heated out very gently. Degradations and side reactions are eliminated.
