摘要： A measuring apparatus, comprising at least a first light source and a second light source for transmitting light; at least one light receiver for receiving light at least of a first received wavelength and a second received wavelength; at least one dispersing element for bending and/or refracting light; wherein the light transmitted by the light sources strikes the dispersing element and is so turned by the dispersing element that it strikes the light receiver. The first light source is arranged at a first angle relative to the dispersing element and the second light source at a second angle relative to the dispersing element, wherein the second angle differs from the first angle. The first angle is so embodied that the wavelength of the light turned by the dispersing element corresponds to the first received wavelength, and wherein the second angle is so embodied that the wavelength of the light turned by the dispersing element corresponds to the second received wavelength.

摘要： A method and analyzer for determining a measured value of a measured variable of process automation technology in a liquid or gaseous medium by means of an optical sensor, which has at least one emitter for sending light of at least two wavelengths, and a receiver associated with the emitter for receiving of received light, comprising the steps as follows: taking a sample of the medium; mixing the sample with one or more reagents; supplying the emitter with an exciter signal for producing the sent light, wherein the sent light by interaction with, especially by absorption by, the mixed sample is converted into received light as a function of the measured variable; producing a receiver signal by means of the receiver from the converted, received light; and determining the measured value based on the receiver signal and a calibration function. The method is characterized in that, in determining the measured value, aging of the reagents is taken into consideration, especially the calibration function includes a term which takes aging of the reagents into consideration.

摘要： An apparatus for determining a value that represents an amount of liquid in a vessel, wherein the vessel is configured to be a tube or a cuvette. The vessel for the liquid is basically transparent, with at least one radiation unit, that is arranged alongside the longitudinal axis of the vessel and that radiates light into the vessel, as well as at least one light detector with at least one light receiver that is assigned to the radiation unit and that receives the light that is coming through the vessel and forwards it to the light detector. The apparatus comprises a data processing unit that determines the value that represents the amount of the liquid in the vessel from the light that was detected by the light detector. The apparatus is characterized in that the light detector detects the sum total of the light that was radiated through the vessel and was received by all light receivers. Furthermore, the invention relates to the use of the apparatus in an analyzer.

摘要： A method for degassing a liquid by means of a piston pump unit having a receiving chamber serving for accommodating the liquid to be degassed and connected with at least one supply line and at least one drain line, and a piston seated in the receiving chamber for performing stroke movements. The piston provides a liquid sealing of the receiving chamber on one end. The following steps are included: drawing liquid via the supply line into the receiving chamber by performing a first stroke movement of the piston in the case of blocked drain line and open supply line; producing a negative pressure in the receiving chamber by continuing the first stroke movement of the piston in the case of blocked supply line and blocked drain line; and opening the drain line and removing a gas phase present in the receiving chamber from the receiving chamber via the drain line by performing a second stroke movement of the piston directed counter to the first stroke movement in the case of an opened drain line and blocked supply line.
