Abstract: An integrated oscillating field ion spectrometry device includes an ionization segment, filtering segment, and detection segment arranged in order. The filtering segment is located after the ionization segment and the detection segment is located after the filtering segment in the carrier gas flow direction. The ionization segment includes an ionizing tool and ionization region electrodes. The carrier gas moves material vapor through the ionizing tool to ionize the material vapor. Two parallel filter electrodes of the filtering segment that receive first DC voltages of opposite polarity and an RF oscillating voltage, filter ions from the carrier gas. Two parallel detector electrodes in the detection segment that are connected to a detection system receive second DC voltages. Ion guidance electrodes surround a periphery of the detector electrodes. The DC voltages and the RF oscillating voltage are selected to optimize detection of the specific ions of interest for a particular application.

Abstract: A non-radioactive plasma ion source device includes at least four planar electrodes that define at least three chambers, including a discharger chamber and at least two additional chambers aligned along a major longitudinal axis of the housing. A discharger ionizes at least one of a transport gas and a discharge gas to form ions in the discharger chamber that are directed by a homogeneous electric field generated by the planar electrodes toward an analyte gas outlet. Ionized species of at least one of the transport gas and the discharge gas that are not entrained by a counterflow gas stream are discharged from the discharger chamber to form a stream of ionized particles that ionize a sample gas and thereby form a stream of ionized analyte particles of the same polarity. The ionized analyte particles are entrained with the stream of ionized particles and pass through an analyte gas outlet to an analyzer.

Abstract: A compact integrated ion mobility based analysis system includes at least one gas chromatograph (GC) column that receives a sample and elutes constituents of the sample where each of the eluted constituents are temporally separated from each other The system also includes at least one ion mobility based sample analyzer that analyzes the eluted constituents based on their ion mobility characteristics. The system further includes a controller that selectively adjusts the temperature within at least one GC column over a period of time and selectively adjusts the temperature within at least one ion mobility based sample analyzer over a period of time.

Abstract: The invention relates generally to ion mobility based systems, methods and devices for analyzing samples and, more particularly, in some embodiments to compact GC-DMS systems, methods, and devices employing enhanced GC column temperature control and configurations to identify various sample constituents.
