摘要： The present disclosure discloses a calibration vessel for an optical immersion sensor to be calibrated, which is designed for measuring, calibrating and/or adjusting a measured variable. The calibration vessel includes a housing having a repeatably tightly sealable opening for introducing the optical immersion sensor. The housing provides a value for a calibration solution. The opening comprises a guide for aligning and positioning the optical immersion sensor to be calibrated in all possible spatial degrees of freedom, wherein the housing is designed such that the influence of the interactions between the light, emitted and received by the sensor, and the housing wall, in particular as a result of scattering, absorption, reflection, phosphorescence and fluorescence, on the measured value that can be ascertained by the sensor is minimal, wherein the volume of the calibration solution is minimized at the same time.

摘要： The present disclosure relates to a sensor arrangement for determining the turbidity of a liquid medium. The sensor arrangement includes a sensor section with at least one light source for sending transmission light into a measuring chamber, and at least one receiver associated with the light source for receiving reception light from the measuring chamber, wherein the transmission light is converted into the reception light in the measuring chamber by the medium by means of scattering at a measurement angle, and the reception light received by the receiver is a measure of the turbidity. The reception light is back reflected at a reflection element in contact with the medium, whereby an optical path from the light source through the measuring chamber to the reflection element and from the reflection element through the measuring chamber to the receiver results.

摘要： A preparation method for preparing spectrometric determinations of a measurand in a target application using a spectrometer is provided. On the basis of reference data recorded in the target application, a normalized measurand master spectrum with a spectral distribution characteristic of the measurand is determined. On the basis of the measurand master spectrum, synthetic spectra are generated which cover a value range greater than or equal to a value range covered by the reference values. On the basis of the synthetic spectra, information for carrying out the spectrometric determinations, including information comprising a property, a wavelength range, and/or a path length range for an optical path length suitable for carrying out the spectrometric determinations, and/or comprising a calculation rule, with which, on the basis of measurement spectra in the target application, measured values of the measurand are determined.

摘要： The present disclosure relates to a method for metering a liquid into a wet chemistry analytical device wherein a specified volume of individual liquids is placed in a metering unit consisting of a metering container and at least one dose measuring device. During the filling of the metering container with the respective liquid, after the activation of the dose measuring device, an additional volume of the liquid is drawn into the metering tube beyond the position of the dose measuring device, wherein during this procedure and afterwards the status of the dose measuring device is checked, and a conclusion is drawn from this regarding the presence of an air bubble-free liquid in the metering tube.
