Abstract
Certain configurations of systems and methods that can detect inorganic ions and organic ions in a sample are described. In some configurations, the system may comprise one, two, three or more mass spectrometer cores. In some instances, the mass spectrometer cores can utilize common components such as gas controllers, processors, power supplies and vacuum pumps. In certain configurations, the systems can be designed to detect both inorganic and organic analytes comprising a mass from about three atomic mass units, four atomic mass units or five atomic mass units up to a mass of about two thousand atomic mass units.
Claims20
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.
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 dual core mass spectrometer configured to select both the inorganic ions and the organic ions.
