An ionising apparatus for ionising a sample of gaseous fluid. The ionising apparatus comprises an ioniser configured to provide reactant ions; an ion modifier configured to modify the reactant ions, and a reaction region arranged to receive the modified reactant ions and a sample and to combine the sample with the modified reactant ions to ionise the sample for analysis by a detector configured to identify a substance of interest in the sample.
