Abstract: A method and apparatus to trap, release and/or separate sample components in solution passing through a channel with or without packing material present by passing ion current through the channel driven by an electric field. A portion of the ion current includes cation and/or anion species generated from second solution flows separated from the sample solution flow path by semipermeable membranes. Cation and/or anion species generated in the second solution flow regions are transferred into the sample solution flow path through ion selective semipermeable membranes. Ion current moving along the sample solution flow path is controlled by varying the composition of the second solutions and/or changing the voltage between membrane sections for a given sample solution composition. The sample composition may also be varied separately or in parallel to enhance trapping, release and/or separation efficiency and range.

Abstract: A multiple function atmospheric pressure ion source interfaced to a mass spectrometer comprises multiple liquid inlet probes configured such that the sprays from two or more probes intersect in a mixing region. Gas phase sample ions or neutral species generated in the spray of one probe can react with reagent gas ions generated from one or more other probes by such ionization methods as Electrospray, photoionization, corona discharge and glow discharge ionization. Reagent ions may be optimally selected to promote such processes as Atmospheric Pressure Chemical Ionization of neutral sample molecules, or charge reduction or electron transfer dissociation of multiply charged sample ions. Selected neutral reagent species can also be introduced into the mixing region to promote charge reduction of multiply charged sample ions through ion-neutral reactions. Different operating modes can be performed alternately or simultaneously, and can be rapidly turned on and off under manual or software control.

Abstract: An apparatus for generating ions includes an Electrospray ionization source configured to provide a spray of charged droplets from a sample solution during operation of the apparatus; an atmospheric pressure chemical ionization (APCI) source including a corona discharge needle configured to produce a corona discharge that further ionizes the spray during operation of the apparatus; and a gas delivery system configured to deliver a gas flow to the corona discharge needle during operation of the apparatus, wherein the gas flow comprises a reagent ion gas which facilitates ionization of the spray by the corona discharge.

Abstract: Electrospray ionization sources interfaced to mass spectrometers have become widely used tools in analytical applications Processes occurring in Electrospray (ES) ionization generally include the addition or removal of a charged species such as II+ or other cation to effect ionization of a sample species. Electrospray includes ionization processes that occur in the liquid and gas phase and in both phases ionization processes require a source or sink for such charged species. Electrolyte species, that aid in oxidation or reduction reactions occurring in Electrospray ionization, are added to sample solutions in many analytical applications to increase the ES ion signal amplitude detected by a mass spectrometer (MS). Electrolyte species that may be required to enhance an upstream sample preparation or separation process may be less compatible with the downstream ES processes and cause reduction in MS signal.

Abstract: The present invention provides a managed or “hosted” service offering that facilitates timely and accurate communication of clinical information, such as critical test results, within a health care environment. The inventive system enables pathologists, laboratory technicians, and laboratory staff to communicate to ordering physicians clinical information (such as lab results) in real-time via a traceable and verifiable communication system. According to the invention, a recipient of the clinical test results is prompted to verify the test results that he or she has just heard to confirm receipt of such results, as well as confirmation that the information provided was properly understood. The read back function ensures that the actual communication of complete clinical information (such as critical tests results) occurs in a seamless, real-time manner.
