摘要： The exemplary embodiments provide a method, system, and device for identifying chemical species in a sample. According to one embodiment, the method, system, and device may include introducing a sample gas into a differential ion mobility device, ionizing at least a portion of the sample gas to generate at least one ion species, filtering the at least one ion species between a pair of filter electrodes, generating a detection signal in response to the at least one ion species depositing a charge on a collector electrode, and detecting a spectral peak associated with the at least one ion species.

摘要： An inlet apparatus is disclosed. The apparatus may include a first conduit for sampling, and a second and third conduit for directing flow throughout the inlet apparatus. Flow may be induced in two opposite directions through the second conduit, which affect the flow of gas through the first conduit for sampling. The various conduits of the apparatus may be connected to a device for inducing flow in different directions. The duration of the flow in a particular direction affects the amount of sample gas that enters a detection device.
