FAIMS Having a Displaceable Electrode for On/Off Operation |
摘要 |
A system for analyzing ions comprises: an ion source; a FAIMS cell comprising: (a) a gas inlet; (b) an outer electrode having a generally concave inner surface and comprising: (i) an ion inlet operable to receive the ions from the ion source and a carrier gas from the gas inlet; and (ii) an ion outlet; and (c) an inner electrode having a conduit therethrough and having a generally convex outer surface that is disposed in a spaced-apart and facing arrangement relative to the inner surface of the outer electrode for defining an ion separation region therebetween; and a mass analyzer for mass analyzing ions transmitted by the FAIMS cell through the ion outlet, wherein the inner electrode is moveable between a first position and a second position, the first position facilitating movement of the ions through the ion separation region, the second position facilitating movement of the ions through the conduit.
