Abstract

A method is provided for calibrating a measurement process for a measurement system having a fluid detector, which is provided with a preconcentrator and a fluid sensor. The measurement system for detecting a concentration of a substance to be detected has a sorption phase, during which the fluid to be detected is enriched for a sorption duration (t) in the preconcentrator in a first state, and a measurement phase, in which a concentration of the substance to be detected resulting from the release of the substance to be detected that was enriched in the preconcentrator is measured. The fluid detector is calibrated by adjusting the sorption duration (t).
