摘要： A system and methods are described for generating reagent ions and product ions for use in a mass spectrometry system. Applications for the system and method are also disclosed for detecting volatile organic compounds in trace concentrations. A microwave or high-frequency RF energy source ionizes particles of a reagent vapor to form reagent ions. The reagent ions enter a chamber, such as a drift chamber, to interact with a fluid sample. An electric field directs the reagent ions and facilitates an interaction with the fluid sample to form product ions. The reagent ions and product ions then exit the chamber under the influence of an electric field for detection by a mass spectrometer module. The system includes various control modules for setting values of system parameters and analysis modules for detection of mass and peak intensity values for ion species during spectrometry and faults within the system.

摘要： A system, components thereof, and methods are described for time-of-flight mass spectrometry. A microwave or high-frequency RF energy source is used to ionize a reagent vapor to form reagent ions. The reagent ions enter a chamber and interact with a fluid sample to form product ions. The reagent ions and product ions are directed to a time-of-flight mass spectrometer module for detection and determination of a mass value for the ions. The time-of-flight mass spectrometer module can include an optical system and an ion beam adjuster for focusing, interrupting, or altering a flow of reagent and product ions according to a specified pattern. The time-of-flight mass spectrometer module can include signal processing techniques to collect and analyze an acquired signal, for example, using statistical signal processing, such as maximum likelihood signal processing.
