Abstract

A process water analysis sampling assembly includes an immersion probe having a first filter unit and a second filter unit which are fluidically separated from each other, a flushing liquid tank, and a fluidics control. The fluidics control includes a pump arrangement which is fluidically connected to each of the first filter unit and the second filter unit, at least two liquid pumps which are arranged to be mutually independent from each other, and a valve arrangement having plurality of switchable valves. The fluidics control controls a sampling and a flushing of the immersion probe. The fluidic control fluidically connects the flushing liquid tank to one of the first filter unit and the second filter unit and simultaneously connects an analysis unit to the other one of the first filter unit and the second filter unit.
