A detector for, and a method of, detecting analytes in gases in described. The detector comprises a sorbent for sorbing therein and/ or thereon and/or desorbing therefrom, an analyte included in a gas exposed thereto, at a zeroth temperature, pressure (T o,P o ), a controller arranged to change the zeroth temperature, pressure (T o,P o ) to a first temperature, pressure (T l, P l ) according to a first equation, to desorb and/or sorb at least some of the analyte; and a sensor arranged to sense at least some of the analyte and to output a response corresponding to the sensed analyte. The response comprises and/or is a characteristic response of the analyte. The first response is modified based on a first baseline response at the zeroth temperature, pressure (T o,P o ).
