    摘要： A method for determining a phosphate concentration in a water sample includes providing the water sample, adding a first acid to the water sample to obtain a second water sample in which a concentration of the first acid is at least 0.5 wt.-%, performing a first photometric measurement of the second water sample, adding a coloring component to the second water sample to obtain a third water sample, performing a second photometric measurement of the third water sample, and calculating the phosphate concentration from a difference between the first photometric measurement and the second photometric measurement.

    摘要： 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.

    摘要： A method for determining a condition indicator of an apparatus includes providing an apparatus configured to measure at least two different technical parameters. A respective parameter value is determined for each of the at least two different technical parameters of the apparatus using at least one sensor configured to determine a respective parameter value for each of the at least two different technical parameters. A respective deviation value of each of the parameter values is determined with respect to an associated respective parameter reference value for each of the technical parameters. A respective deviation relevance value is determined from each of the deviation values using a respective parameter-specific deviation relevance function for each of the parameter values, the parameter-specific deviation relevance functions being different from each other. Using an indicator function, a condition indicator is calculated from the determined deviation relevance values. An overall condition of the apparatus is calculated using the condition indicator.
