摘要:
A mobile water analyzing system for determining an analyte in a water sample includes a basic unit and a test element configured to be inserted into the basic unit. The test element includes a sample line with an inlet opening configured to receive the water sample, a measuring section forming a measuring track and configured to allow the determination of an analyte, a pump opening, and a key reagent disposed inside the sample line. The basic unit includes a test element receptacle configured to hold the inserted test element, an analyzer with an analyzer measuring track formed by the measuring section, and a pump actuator cooperatively connected with the pump opening.
摘要:
A basic unit for a mobile water analyzing system includes a photometer, a test element receptacle, a photometric measuring track, and a pump actuator. The photometer comprises a light source configured to generate a measurement beam and a light detector configured to receive the measurement beam. The test element receptacle is configured so as to allow a separate test element comprising a measuring section and a pump port to be inserted into the test element receptacle. The photometric measuring track is defined by the measuring section when the separate test element is inserted into the test element receptacle. The measurement beam and the photometric measuring track are aligned during a photometric measurement so that a photometric measurement occurs along a longitudinal length of each of the photometric measuring track and the measuring section. The pump actuator is cooperatively connected with the pump port.

A method for determining an analyte in a water sample with a mobile water analyzing system having a basic unit and a test element insertable in the basic unit, the method comprising providing the test element and the basic unit. The test element is inserted into a test element receptacle of the basic unit. The water sample is transported forward from an inlet opening to a measuring section of the test element. A first analyzing of the water sample is performed in the measuring section with an analyzer of the basic unit. The water sample is transported forward from the measuring section to the first reagent section of the test element. The water sample is transported backward from the first reagent section to the measuring section of the test element. A second analyzing of the water sample is performed in the measuring section with the analyzer of the basic unit.

A water analysis device with a pneumatically actuated multi-chamber peristaltic pump includes a base plate comprising a plurality of proximally open pump chambers disposed on a proximal side of the base plate. A pump membrane disposed on the proximal side of the base plate is configured to close the pump chambers. A cover plate is disposed on the pump membrane comprising a respective pneumatic actuator channel in a region of each of the pump chambers. The pneumatic actuator channel is configured to connect to an overpressure source which actuates the pump membrane. A connection channel formed as a groove on a distal side of the base plate is disposed between two of the pump chambers. A separate groove cover is disposed on the distal side of the base plate in a region of the groove. The separate groove cover closes a distal opening side of the groove.

A process analyzer for detection of an analyte in a liquid under analysis includes a base module and an exchangeable cartridge module. The exchangeable cartridge module comprises a sample taking device comprising a membrane configured to obtain a sample from the liquid under analysis. A first pump mechanism is configured to pump the sample away from the sample taking device. A second pump mechanism is configured to introduce a reagent into the sample. A measuring section is configured to perform a quantitative detection of the analyte in the sample. A degassing device is arranged downstream of the first pump mechanism and the second pump mechanism. The degassing device is configured to degas the sample.
