摘要： A method and system is presented for accurately measuring the two phase flow rate of a fluid mixture that includes two different phase components. Capacitance tomography measurements are made in order to determine the concentration ratio of the different phase components within the fluid. Approximate flow measurements are made by transmitting, for example, ultrasound waves through the fluid mixture, and measuring the different speeds of propagation of the ultrasound waves through the different phase components of the fluid mixture. The exact flow rate of the fluid mixture is determined using the concentration ratio obtained from the tomographic measurements, and the approximate flow measurements made, for example, by ultrasound sensing.

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.
