Mobile water analysis arrangement and method for determining an analyte in a water sample
First Claim
1. A mobile water analyzing system for determining an analyte in a water sample, the mobile water analyzing system comprising:
- a basic unit and a test element configured to be inserted into the basic unit, whereby the test element comprises;
a microfluidic sample line comprising;
an inlet opening disposed at a first end, the inlet opening being configured to receive the water sample,a pump port disposed at a second end of the sample line,an inlet section disposed between the inlet opening and the pump port,a measuring section comprising at least one window arranged at an end of the measuring section, the measuring section being arranged between the inlet section and the pump port and being coincident with a sample pathway, anda key reagent disposed in the sample line; and
whereby the basic unit comprises;
a photometer comprising a light source configured to generate a measurement beam and a light detector configured to receive the measurement beam,a test element receptacle configured so as to allow the test element to be inserted into the test element receptacle,a photometric measuring track, the photometric measuring track being defined by the measuring section when the test element is inserted into the test element receptacle, the measurement beam and the photometric measuring track being aligned during a photometric measurement so that a photometric measurement occurs along a length of each of the photometric measuring track and the measuring section, and not in a cross direction thereto, anda pump actuator cooperatively connected with the pump port.
