Abstract: Systems and methods are disclosed for calibrating mass spectrometers. In accordance with one implementation, a system comprises a calibrant chamber within a housing of a mass spectrometer. The system also comprises a permeation tube enclosed within the calibrant chamber, wherein the tube contains a calibrant chemical that continuously outgasses the calibrant chemical. The outgassed calibrant chemical may be introduced to the mass spectrometer for analysis. The system may also comprise a heating block to control the temperature of the calibrant chemical. The system may further comprise a valve that introduces a known amount of the calibrant chemical into the calibrant chamber. In accordance with the present disclosure, systems and methods are provided for calibrating a mass spectrometer abundance scale.

Abstract: A chemical pre-concentrator includes a conduit defining a flow path between two ends and having a heating element disposed within the conduit, such that the heating element has at least one sorbent material deposited directly on at least a portion of a conductive surface of the heating element. Some such heating elements are in the form of electrically conductive strips defining both a plurality of apertures through the strip and a series of undulations spaced along the flow path.

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).
