文摘

Solution-cathode glow discharge used as an ionization source for mass spectrometry. SCGD-MS can provide atomic as well as intact molecular mass spectra. Atomic limits of detection range from 0.1 to 4 ppb. Molecular ions can be controllably fragmented by adjusting the SCGD power. SCGD can also be used as an ambient desorption/ionization source.
