Abstract
A reservoir (4) for the working fluid of the saturation unit (3) is connected with a sampling section (1) by a pressure equalization line (9) of the gas that is loaded with solid particles, as a result of which a sucking back of the working fluid from the reservoir (4) into the sampling section (1) and other sections of the measurement environment that are connected with such are prevented, even in the presence of unfavorable pressure conditions.
