Abstract
A method and apparatus for detecting a flow disruption within a gas chromatograph (GC) inlet. A controller controls an input flow of a gas entering a chamber of the GC inlet, and the output flow of gas leaving the chamber. A flow disruption is detected when at least one of the input and output flows deviates from a target value.
