Abstract (en)
[origin: WO9921212A1] A "cold" ion mobility spectrometer (IMS) device (100) deliberately operates at a temperature low enough that sample vapors condense, i.e., are trapped, in the IMS (100) after their introduction with a condensing liner (117) in a reaction region (102) of the IMS (100). The deliberate trapping of the vapors in the IMS (100) effectively removes the sample from the ionization process because after condensation, the vapor pressure of the compound at the operating temperature of the IMS (100) is negligible. Since the compound is no longer present in vapor form, ion production no longer takes place at a sufficient rate to be detectable.
