    摘要: 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 H+ 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. A new set of Electrolytes has been found that increases positive and negative polarity analyte ion signal measured in ESMS analysis when compared with analyte ESMS signal achieved using more conventional electrolytes. The new electrolyte species increase ES MS signal when added directly to a sample solution or when added to a second solution flow in an Electrospray membrane probe. The new electrolytes can also be added to a reagent ion source configured in a combination Atmospheric pressure ion source to improve ionization efficiency.

    摘要: The invention provides a method and apparatus for trapping, releasing and/or separating 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 comprises cation and/or anion species generated from second solution flows separated from the sample solution flow path by semipermeable membranes. Cation and/or Anion ion 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. The invention when interfaced to an Atmospheric Pressure Ion Source, that may include Electrospray Ionization, with mass spectrometric analysis enables independent control of the on-line sample separation process and the Atmospheric Pressure Ion Source or Electrospray ionization processes.

    摘要: 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.
