Publication number: 20110309243Abstract: 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.Type: ApplicationFiled: August 26, 2011Publication date: December 22, 2011Applicants: CHEM-SPACE ASSOCIATES, INC., PERKINELMER HEALTH SCIENCES, INC.Inventors: Craig Whitehouse, Thomas White, Ross Willoughby, Ed Sheehan

Patent number: 8080783Abstract: 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.Type: GrantFiled: February 10, 2009Date of Patent: December 20, 2011Assignees: PerkinElmer Health Sciences, Inc., CHEMSPACE Associates, Inc.Inventors: Craig Whitehouse, Thomas White, Ross Willoughby, Ed Sheehan

Patent number: 5627453Abstract: A rechargeable battery pack including a microcontroller connected to a voltage measuring circuit and a current measuring circuit for measuring, respectively, the voltage across and the current flowing from a battery. Upon each expiration of a predefined time period during each discharge cycle of the battery, the microcontroller computes the product of the voltage, the current, and the length of the time period, thereby computing the energy expended by the battery over each period of time. An energy variable stored in a nonvolatile memory device associated with the microcontroller for representing the total amount of energy output by the battery over the life thereof is incremented by the computed energy. In one embodiment, a temperature sensing circuit measures the temperature of the battery and the instantaneous energy is adjusted by a temperature factor associated by the measured temperature before being used to increment the value of the energy variable.Type: GrantFiled: January 11, 1995Date of Patent: May 6, 1997Assignee: Dell USA, L.P.Inventors: Ed Sheehan, Leslie Thompson
