摘要： A method of removing sample residue from a surface of a mass spectrometer inlet, with the surface being adjacent to an ion passageway, is provided. A pendent droplet of a cleaning solvent is formed at a tip of a capillary, with the tip being spaced apart from the surface. The pendent droplet detaches from the tip and contacts the surface. The surface is heated to a temperature T at least 50° C. above the boiling point of the least volatile component of the cleaning solvent.

摘要： A liquid sample analyzing system including an ion analyzer having a first ion source receiving a target sample and a second ion source receiving a reference sample; a liquid sample introduction mechanism 3 including a passage-switching section introducing reference samples into the second ion source; and a controller for repeatedly performing a series of steps in the ion analyzer, the steps including: a pre-measurement step for initiating a measurement; a measurement step for introducing a target sample into the first ion source and performing a measurement on an ion originating from the target sample along with an ion originating from a reference sample introduced into the second ion source by the liquid sample introduction mechanism; and a post-measurement step where the liquid sample introduction mechanism operates concurrently with the predetermined post-measurement step to switch the passage-switching section to a passage having a reference sample for the next analysis.

摘要： 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.

摘要： A dual source ionizer includes a first ionization source and a second ionization source. The first ionization source is configured to generate a first electric field. The first electric field has a first field strength that is insufficient to form NOx− ions. The second ionization source is configured to generate a second electric field. The second electric field has a second field strength that is sufficient to form ozone and the NOx− ions.
