Ion Mobility Spectrometer Comprising Two Drift Chambers

摘要

ion mobility spectrometer with two drift chambers (11 and 12) and one common doping reaction zone (2) has a . Each drift chamber to take the same way to break down by the high electric field ion doped , and includes ion reformer (14 , 24) . One chamber of the drift chamber (11) is doped and the other of the chamber 12 is not doped . In this way, the dopant adducts are removed by the modification process and then recombined with the dopant chamber 11 only in the doped , by two drift chambers so that different outputs are generated . ; ion mobility spectrometer , doped drift chamber , an ion reformer
