Abstract
A gas chromatograph-mass spectrometer (GC-MS) system includes a multi-capillary GC column coupled to a mass analyzer through an ionization interface. The ionization interface includes an ionization device and an ion guide configured for receiving a high-capacity gas-sample flow from the GC column and transmitting a compressed ion beam to the mass analyzer. The ion beam may be converging.
