Mass flow control in a process gas analyzer

摘要

A sample conditioner system carries a real-time sample of a process gas through a chromatograph column in an analyzer. A flame ionization detector (FID) is coupled to the chromatograph column and generates a temperature output and an output indicating sample ions. A processor generates a real-time process gas analysis and a mass set point. A flow controller controls mass flow of a stream of gas to the FID.
