1. A method for calibrating a measurement process for a measurement system for detecting a concentration of a substance to be detected,
wherein the measurement system comprises a fluid detector comprising:
a preconcentrator; and
a fluid sensor,
wherein the measurement system is configured to have a sorption phase and a measurement phase, being operable by a control unit;
to enrich the fluid to be detected during the sorption phase for a sorption duration (t) in the preconcentrator in a first state, and
to measure a concentration of the substance to be detected resulting from the release of the substance to be detected that was enriched in the preconcentrator, during the measurement phase, the method comprising:
calibrating the fluid detector by adjusting the sorption duration (t) in the control unit.
