Claim 12:
13. A method of detecting analytes in gas-phase, comprising:
exposing a first sorb ent of a set of sorbents, wherein the first sorbent comprises and/or is a microporous and/or mesoporous dielectric or semiconducting material such as silica, a zeolite, activated carbon and/or a metal organic framework, MOF, to a first gas of a set of gases, at a zeroth temperature, pressure (T0, P0) of a set of temperatures, pressures (T, P), wherein the first gas is ambient air;
cooling the first sorbent to the zeroth temperature (T0) and sorbing by the first sorbent, therein and/or thereon, a first analyte of a set of analytes included in the first gas;
desorbing and/or sorbing at least some of the first analyte by controlling a change from the zeroth temperature, pressure (T0, P0) to a first temperature, pressure (T1, P1) of the set of temperatures, pressures (T, P) according to a first equation of a set of equations;
sensing, by a sensor, at least some of the first analyte and outputting a first response of a set of responses corresponding to the sensed first analyte, wherein the sensor comprises and/or is a broadband analyte detector such as a photoionization detector, PID; and
obtaining a first baseline response of a set of baseline responses at the zeroth temperature, pressure (T0, P0) and modifying the first response based, at least in part, on the obtained first baseline response;
wherein the first response comprises and/or is a first characteristic response of a set of characteristic responses of the first analyte.
