Abstract
An ion detection assembly is described that includes a drift chamber, an inlet assembly, and a collector assembly. The drift chamber is formed of substantially non-conductive material and/or semi-conductive material. A patterned resistive trace is deposited on one or more of an interior surface or an exterior surface of the drift chamber. The patterned resistive trace is configured to connect to a source of electrical energy. The inlet assembly and the collector assembly are in fluid communication with the drift chamber. The inlet assembly includes an inlet for receiving a sample, a reaction region for ionizing the sample, and a gate for controlling entrance of the ionized sample to the drift chamber. The collector assembly includes a collector plate for collecting the ionized sample after the ionized sample passes through the drift chamber.
