Gas extraction is the ideal method to handle oils, solid and pasty substances. The heating module for oils is an extension module of AQUA 40.00. Oil samples are injected through the septum into the heating oven. It is possible to apply sample volumes ranging up to 20 ml. The high sensitivity of the AQUA 40.00 system allows precise detection of the moisture down to 1 ppm range. After analysis, the used oil sample flows off through the 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.
Heating with temperature program reveals in which way the moisture in question is bonded to the sample substance.
