摘要： A method for the determination of a plausibility of a measurement result of a determination of an ammonium content of an aqueous sample. The method includes providing a blue indole dye mixture of the aqueous sample, determining a first extinction value of the blue indole dye mixture in a first absorption region, determining a second extinction value of the blue indole dye mixture in a second absorption region, dividing the first extinction value by the second extinction value so as to obtain a quotient, and determining the measurement result to not be plausible if the quotient ≥ 1.1.

摘要： The invention refers to an optical measurement apparatus (10) with an optical device (18,20,22) and a liquid sample vessel (12) for measuring an optical parameter of a liquid sample (13) in the liquid sample vessel (12), comprising a drying circuit circulating drying air for venting the sample vessel (12), wherein the drying circuit comprises a mechanical water stop means (100) in the course of the drying circuit, the water stop means (100) comprising a conduit body (102) with a water-absorbing swelling element (120) arranged within the conduit body (102). The water stop means is simple and inexpensive and reliably protects all elements downstream of the water stop means from a water ingress upstream of the water stop means.

摘要： An optical measurement device with a transparent cylindrical measurement cuvette, which defines an axial symmetrical axis and contains the fluid sample, an optical measurement arrangement which quantitatively determines the optical property of the fluid sample in the measurement cuvette, and a mechanical cleaning arrangement is described. The cleaning arrangement comprises an external magnetic working platform, which is arranged coaxially to the symmetrical axis, is slidable in a translatory manner parallel to the symmetrical axis, is rotatable about the symmetrical axis, encloses the cylindrical measurement cuvette externally in an annular manner, and has at least one translatory magnet element and at least one rotary magnet element, and an internal magnetic cleaning unit, which is arranged within the measurement cuvette and is slidable in a translatory manner, has a cleaning body, has at least one translatory magnet element, and has at least one rotary magnet element. The translatory magnet elements as well as the rotary magnet elements of the working platform and the cleaning unit are coupled to one another in a contactless and magnetic manner, respectively. Other aspects are described and claimed.

摘要： A water analysis device having a light source and a light detector for detecting an optical parameter of a water sample in a transparent measuring cell is disclosed. A ventilation circuit for ventilating a cell chamber is provided, wherein there is a differential pressure of at least 2.0 mbar between the cell chamber and the atmosphere when a ventilation pump is operated. The device housing forms the cell chamber which is fluidically sealed by a cover assembly. The cover assembly and the device housing have a mechanism that mimics the sealing action of a turn-lock fastener, such that the cover assembly can be secured to and/or released from the device housing by means of a rotational movement. The cover assembly and the device housing form an annular ring seal which is coaxial with the rotational movement and which is formed by an elastic sealing body having a circular sealing lip and a correspondingly circular shoulder seat on which the sealing lip is pressed due to the atmospheric differential pressure. Other aspects are disclosed and claimed.
