Patent ID: 7144741

Claim:
Process for the determination of parameters of a breath condensate by using at least one sensor for the measurement of the parameters and an analysis unit with display of the measurement results, comprising the steps of delivering a solution from a storage container and applying said solution onto the at least one sensor within a closed cassette including the at least one sensor by action on the storage container from outside the cassette on the storage containers, the solution generating at least one of a cassette flushing; a conditioning of the at least one sensor; a calibration of the at least one sensor; and a dilution of a sample solution and/or elevation of the ion concentration or conductivity; applying through an opening of the cassette a breath condensate sample solution onto the at least one sensor for parameter determination; and coordinating the temperature of the at least one sensor with a temperature of the sample solution during determination of the parameters of the breath condensate, by adjusting the temperature of the sample solution to the working temperature of the at least one sensor; transmitting measurement results originating from the at least one sensor out of the cassette and to the analysis unit whereby data apart from the pure measurement data, selected from the group consisting of flow rate, temperature, freedom from air bubbles and, time are captured and transmitted to the analysis unit; and disposing the cassette after the determination of parameters of the breath condensate and of a sample solution without release of any solution in the cassette.
