CHEMICAL IONIZATION REACTION OR PROTON TRANSFER REACTION MASS SPECTROMETRY WITH A QUADRUPOLE OR TIME-OF-FLIGHT MASS SPECTROMETER

摘要

The reagent ions and the ion generating system for use in mass spectrometry is described a system and method for generating. Applications for a system and method for detecting a very small amount of volatile organic compounds in concentrations disclosed. Microwave or radio frequency RF energy source to ionize the particles of the gaseous reagents to form reagent ions. Reagent ions are entered into the drift chamber, such as chamber and the fluid sample interacts. Electric field, controls the reagent ions, to facilitate the interaction with the fluid sample to form an ion generation. Then, the reagent ions and the ions generated are output from the chamber by the effect of the electric field for detection by the mass spectrometer module. Mass spectroscopy analysis system includes a module for detecting a defect in the mass and the peak intensity values ​​and the system of ion species for analysis by mass and various control modules for setting the values ​​of the system parameters.
