ION MOBILITY SPECTROMETRY (IMS) DEVICE WITH CHARGED MATERIAL TRANSPORTATION CHAMBER Russian patent published in 2019 - IPC G01N27/62 

FIELD: instrument engineering.

SUBSTANCE: use: to separate and identify materials. Essence of the invention lies in the fact that the ion detection assembly contains a drift chamber, an inlet assembly and a collector assembly, the drift chamber is made from essentially non-conductive material and/or semiconducting material, a patterned resistive trace is deposited to one or both of the interior surface and the exterior surface of the drift chamber, the patterned resistive trace is made with the ability to connect to a source of electrical energy, the inlet assembly and the collector assembly are in flow communication with the drift chamber, the inlet assembly contains an inlet port for receiving a sample, a reaction region for ionizing the sample and a gate for controlling the entrance of the ionized sample into the drift chamber, the collector assembly includes a collector plate for collecting the ionized sample after passing through the drift chamber.

EFFECT: providing the possibility of uniform and stable resistance, which improves the quality of detection.
