1. A method of sequentially detecting inorganic ions and organic ions using a mass analyzer fluidically coupled to an ionization core, the method comprising sequentially selecting (i) ions from the inorganic ions received from the ionization core and (ii) ions from the organic ions received from the ionization core, in which the mass analyzer comprises a first single core mass spectrometer and a second single core mass spectrometer each configured to use a common processor, a common power source and at least one common vacuum pump, wherein the first single core mass spectrometer is configured to select the ions from the inorganic ions received from the ionization core and the second single core mass spectrometer is configured to select the ions from the organic ions received from the ionization core.
