Abstract: A mass spectrometer for analyzing a sample may include an analysis chamber for analyzing the sample and a first vacuum pump operably connected to the analysis chamber, wherein the first vacuum pump operates to create a first vacuum state. The mass spectrometer may also include a sample-preparation chamber operably connected to the analysis chamber and a second vacuum pump that operates to create a second vacuum state, wherein the first vacuum state is a lower pressure than the second vacuum state. The second vacuum pump may be operably connected to the first vacuum pump in a first configuration, and the second vacuum pump may be operably connected to the sample-preparation chamber in a second configuration.

Abstract: Systems and methods for automatic gain control in mass spectrometers are disclosed. An exemplary system may include a mass spectrometer, comprising a lens configured to receive a supply of ions, and a mass analyzer. The mass analyzer may include an ion trap for trapping the supplied ions. The mass analyzer may also include an ion detector for detecting ions that exit the ion trap. The lens may focus the ions non-uniformly based on mass of the ions to compensate for space charge effects reflected in a measurement output of the mass spectrometer.

Abstract: Processing a liquid sample (204) having an analyte (206) by reducing a pressure in a container (200) including the liquid sample to less than atmospheric pressure and maintaining a reduced pressure in the container. Reducing the pressure in the container (200) and optionally agitating the liquid sample increases an amount of vapor-phase analyte (206) above the liquid sample. In some cases, a concentration of the vapor-phase analyte is further increased, for example, with a chemical trap (502). The vapor-phase analyte can be provided to a chemical analyzer (302).

Abstract: Methods, devices, and systems are disclosed for releasing a sample from a carrier medium. A method of releasing a sample from a carrier medium comprises treating a sample on a carrier medium with a first organic reagent, wherein when the sample contains at least one inorganic salt, the first organic reagent binds to a cation of the inorganic salt to produce both a first volatile compound and an isolated anion of the inorganic salt; treating the sample on the carrier medium with a second organic reagent, wherein the second organic reagent reacts with the isolated anion to produce a second volatile compound; and releasing the treated sample from the carrier medium, wherein when the first and the second volatile compounds are produced, the releasing step releases at least one of the first and second volatile compounds from the carrier medium.
