Publication number: 20210003539Abstract: A thermal modulator for gas chromatography includes an analytical capillary to be traversed by analytes and that is interposed between two gas chromatographic columns; a cooling system having a cold zone, a support element associated with the cold zone and supporting a portion of the analytical capillary at a corresponding or slightly higher temperature than the cold zone, so as to define a trapping portion of the analytes; a control system, which selectively controls the emission of pulsed current to electrically conductive elements associated with the analytical capillary to heat the trapping portion and cause the release or desorption of previously immobilized analytes; and a heating system of a portion of the analytical capillary, positioned outside of the support element and upstream of the support element, so as to generate a rapid expansion of the gas contained in the portion and facilitate the advancement of the released or desorbed analytes.Type: ApplicationFiled: March 19, 2019Publication date: January 7, 2021Inventors: William W.

Patent number: 9044747Abstract: An improved process for regenerating ion exchange resin, includes a regeneration step of displacing captured ions from the resin to regenerate its ion-capture functionality, followed by one or more fluid-employing post-regeneration steps such as a fluid displacement or rinse, a fluid transporting or mixing, and a rinse down to quality. To avoid problems of early leakage of weakly held ions such as boron, the post-chemical or postdisplacement steps use water that is essentially free of boron, or otherwise avoid localized contamination in the regenerated resin which is used in bottles or beds (30). A two-stage polish may be operated with modified lead/lag bottles. A detector (D) for an indicator condition (conductivity, silica breakthrough) between stages determines when to shift the lag bottle forward, and periodically both bottles are replaced.Type: GrantFiled: May 12, 2012Date of Patent: June 2, 2015Assignee: General Electric CompanyInventors: William W. Carson, Charles Dale, William D. McClain, Robert J. Ritz, Charles Swenson

Patent number: 8920658Abstract: Methods and apparatus for desolvating flowing liquid streams while retaining temporal resolution of dissolved substrates are disclosed. A novel small-scale self-regulating spray dryer preserves temporal resolution while desolvating a liquid chromatography eluent stream and depositing the solute onto an optical surface for infrared spectrographic analysis. The liquid eluent is pumped through a heated nebulizer to create a high-speed jet of solute containing liquid and solvent vapor. This jet is directed circumferentially inside a hot cylindrical cavity. Centrifugal force causes the larger liquid droplets to travel along the outer diameter of the cavity. The cavity surface is heated to cause the droplets to film boil. Film boiling reduces droplet contact with the cavity surface thereby retaining the solute in the droplets. The solute temperature is limited by controlling the pressure into which the solvent evaporates from the droplets.Type: GrantFiled: February 21, 2014Date of Patent: December 30, 2014Assignee: Spectra Analysis Instruments, Inc.Inventors: William W. Carson, Sidney Bourne

Patent number: 8142633Abstract: A treatment system and method for continuous deionization of a biologically derived feed stream includes a plurality of electrodialysis units (3, 9, 10, 11, 12, 13) arranged in stages along a treatment line, and stages are controlled such that the feed stream attains a certain quality before entering the next stage. The feed and concentrate streams move in generally opposite sense along the line, matching fluid characteristics of dilute and concentrate cells. The treatment line has two or more stages. Systems may have phased staging operations, and cell constructions may adapt the electrodialysis units for enhanced processing of difficult process fluids. A controller sets operating potentials in different electrical stages, and simple control parameters optimize ion removal and current efficiency without polarization of the fluid. The invention also includes phased staging of reversal operation, and cell constructions or fillings that adapt the treatment cells for enhanced processing.Type: GrantFiled: October 27, 2004Date of Patent: March 27, 2012Assignee: GE Ionics, Inc.Inventors: Bruce Batchelder, Li Zhang, William W.

Patent number: 7794577Abstract: A spacer element (1) is disclosed having an integral screen for use in filled cell electrodialysis. The spacer (1) has a continuous portion (2) impermeable to flow and a screen (3) which spans a centrally-located flow treatment region that contains active treatment material, such as ion exchange beads. The screen (3) may perform a structural function, allowing operation at elevated pressure, and may also define a minimum gap between adjacent membranes and enhance mixing along the flow path and at cell boundaries. The spacer element (1) may be configured to enhance hydraulic filling of the cells, and cell architecture is readily implemented in a wide range of useful flow path geometries utilizing the screen spacer element (1).Type: GrantFiled: November 16, 2002Date of Patent: September 14, 2010Assignee: Ionics, IncorporatedInventors: William W.
