Online water determination in petroleum products
The gas extraction is the ideal method to detect moisture in oil samples and viscous substances. 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 20mL 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 avalve 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 moisture desorption from the sample. Moreover, sensitive samples can be heated out very gently. Degradations and
side reactions are eliminated.

The sample ways are coupled directly with monitoring process. Thereby the oil sample is transferred into the oil module without any contamination. The sample transfer
can be adjusted to an automatic procedure. The control systemis adjustable for various parameters:
• Delivery rate of dosing pump
• Rinsing steps
• Emptying of oil chamber
