Abstract:
The invention provides improved apparatus for, and methods of, ionizing analyte molecules in a flow of gas, typically at or around atmospheric pressure. The invention may be used to facilitate mass spectrometric analysis of analytes comprised in the effluent form a gas chromatograph. Ionization may be effected by atmospheric pressure chemical ionization or by atmospheric pressure photo ionization.
