An ion trap mobility spectrometer calibration system and method wherein the maximum response of the spectrometer is determined. A quantity Q<SUB>0 </SUB>is chosen representing a response which is a predetermined percentage of the maximum response. Input to the ion trap mobility spectrometer are at least two known quantities Q<SUB>1 </SUB>and Q<SUB>2 </SUB>of an analyte, which have a predetermined relationship with Q<SUB>0</SUB>. The responses corresponding to R<SUB>1 </SUB>and R<SUB>2 </SUB>of the ion trap mobility spectrometer are observed based on the respective inputs of quantities Q<SUB>1 </SUB>and Q<SUB>2</SUB>. R<SUB>1</SUB>, R<SUB>2</SUB>, and Q<SUB>1 </SUB>and Q<SUB>2 </SUB>are then used to calculate the calibration constants in an equation describing a curve where the response of the ion trap mobility spectrometer is a function of the quantity of the analyte input therein. The calculated calibration constants are input to thereafter determine, from the response, the quantity of a detected analyte based on the equation.
