Patent ID: 8377709

Claim:
A device for the chromatographic detection of a substance, the device comprising: a housing with a test strip area; a test strip provided with a detection reagent for detection of the substance; an optoelectronic scanning system for optoelectronically scanning the test strip, the optoelectronic scanning system being supported by the housing; a reservoir containing developer fluid for penetration into the test strip to bring about a detection reaction, the reservoir being supported by the housing for providing developer fluid from the reservoir to the test strip area; a process control system connected to an actuator for opening the reservoir and connected to the optoelectronic scanning system for exposure of the test strip to the developer fluid by controlling emptying of the reservoir to provide developer fluid from the reservoir to the test strip area and for analysis of the detection reaction with the optoelectronic scanning system; an inclination sensor for detecting the orientation of the housing with the test strip area with respect to a direction of the force of gravity and generating a measurement signal, the inclination sensor being connected to the process control system; and a processor unit connected to the process control system for generating a shut-off signal or interruption signal for the process control system from the measurement signal of the inclination sensor if a limit value is exceeded.
