  • Patent number: 9625435
    Abstract: 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.

  • Patent number: 9052302
    Abstract: 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.

  • Patent number: 8881580
    Abstract: A process analysis unit includes a base module and an exchangeable cartridge module. The base module comprises at least one independent pump drive, and an analyte sensor without a fluidic measuring section. The cartridge module comprises a liquid reservoir tank, a sample taking device, at least one drive-less pump mechanism configured as a peristaltic membrane pump, a fluidic measuring section for the analyte sensor, and a plastic material plate with groove-like microfluidic channels configured to connect the liquid reservoir tank, the at least one drive-less pump mechanism, and a measuring section. The drive-less pump mechanism is driven pneumatically and pumps a liquid from the liquid reservoir tank. When the cartridge module is connected to the base module, the at least one drive-less pump mechanism is connected to and is driven by the at least one independent pump drive, and the fluidic measuring section is connected to the analyte sensor.
