摘要

And describes a system and method for generating product ions and reagent ions for use in mass spectrometry systems. Also described the application of the present system and method for detecting volatile organic compounds very minute concentration. The ionized particles of the reagent vapor, high frequency RF energy source or microwave, to form reagent ions. Flows into the chamber, such as the drift chamber, reagent ions interact with the fluid sample. Field induces reagent ions to form product ions and to promote the interaction with the fluid sample. Then, for detection by mass spectrometer modules, product ions and reagent ions, flowing out from the chamber under the influence of an electric field. The system includes an analysis module for the detection of anomalies in the system and internal control of various modules to set the value of the system parameter, as well as the detection of the peak intensity value and the mass of the ion species in the spectral analysis.
