    摘要: The invention described herein provides a mass spectrometry system, having an ion source including an ionization device for producing ions, a collection conduit adjacent to the ionization device for collecting ions produced by the ionization device, a first gas source for supplying gas to desolvate ions produced by the ionization device, a second gas source for supplying gas at a defined flow to the ionization region, and a detector downstream from the ion source for detecting ions produced by the ion source. The invention also provides an ion source including an ionization device for producing ions, a collection conduit adjacent to the ionization device for collecting ions produced by the ionization device, a first gas source for supplying gas to desolvate ions produced by the ionization device, and a second gas source for supplying gas at a defined flow to the ionization region. A method for producing analyte ions is also disclosed. The method includes producing analyte ions from an ionization device, directing a first heated gas toward the analyte ions to desolvate the analyte ions, and directing a second gas toward the analyte ions at a defined and continual flow rate.

    摘要: The subject invention includes constituent separation apparatuses that include a fluid pathway and a pair of spaced-apart electrodes positioned within the pathway for detecting current flow within a mobile phase present in the pathway. Coupled to the pair of spaced-apart electrodes is a mix ratio determinator for determining the mix ratio of the mobile phase from the detected current flow. Also provided are methods that include contacting a mobile phase with an apparatus for separating constituents of a mobile phase, detecting the current flow of the mobile phase when the mobile phase is in contact with the apparatus and determining the mix ratio of the mobile phase from the detected current flow. The mix ratio may be adjusted based on the determined mix ratio. Algorithms for practicing the subject methods are also provided on computer readable mediums. Systems and kits for practicing the subject methods are also provided.

    摘要: A system for controlling fluid flow in a microfluidic circuit includes at least one microfluidic channel having a first fluid, a switch element coupled to the microfluidic channel, the switch element comprising at least one inlet, at least one outlet and a second fluid, the second fluid being immiscible with respect to the first fluid. The system also includes an actuator configured to alter the position of the second fluid, such that when in a first position, the second fluid allows the first fluid to flow from the at least one inlet to the at least one outlet, and such that when in a second position, the second fluid prevents the first fluid from flowing from the at least one inlet to the at least one outlet.
