Abstract
Provided herein is an ion source containing a plurality of components, at least one of which is partially coated with a layer of silicon. The ion source reduces reactivity between the sample and the carrier gas, reduces or eliminates tailing in ion chromatograms, and/or improves mass spectral fidelity. Also provided are methods of using the ion source in a mass spectrometer or gas chromatograph-mass spectrometer.
