Raymond P. W. Scott has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Light detector apparatus
    Patent number: 5073345
    Abstract: A light absorption detector includes a light source substantially adjacent a window of a chromatogrpahic flow cell. The flow cell is defined by a housing member which also includes a photo-sensitive detector.
    Type: Grant
    Filed: July 9, 1985
    Date of Patent: December 17, 1991
    Assignee: The Perkin Elmer Corporation
    Inventors: Raymond P. W. Scott, Gary J. Schmidt
  • Low dispersion fluid conduit useful in chromatography systems
    Patent number: 5032283
    Abstract: A fluid conduit including a tube having a two-dimensional serpentine opening therethrough and exhibiting low peak dispersion is applicable as an extra-column connection.
    Type: Grant
    Filed: July 3, 1986
    Date of Patent: July 16, 1991
    Assignee: The Perkin Elmer Corporation
    Inventors: Raymond P. W. Scott, Elena Katz
  • Ionization detectors for gas chromatography
    Patent number: 4873862
    Abstract: It has been discovered that a glass envelope at elevated temperature containing a noble gas will result in electrons being evolved. The phenomenon has been employed to construct both argon and helium detectors for gas chromatography.
    Type: Grant
    Filed: January 9, 1987
    Date of Patent: October 17, 1989
    Assignee: The Perkin-Elmer Corporation
    Inventors: Raymond P. W. Scott, Elena Katz
  • Sample cell temperature stabilizer
    Patent number: 4598765
    Abstract: An apparatus for modifying the temperature of the effluent of a fluid stream entering a flow cell which includes a counterflow heat exchange between the outlet fluid and the inlet fluid and a thermally equilibrating the flow cell with the inlet fluid after it has passed through the counterflow heat exchange and before it enters the flow cell.
    Type: Grant
    Filed: February 3, 1984
    Date of Patent: July 8, 1986
    Assignee: The Perkin-Elmer Corporation
    Inventors: John Atwood, Charles Helms, Raymond P. W. Scott
  • Sample cell temperature stabilizer
    Patent number: 4589477
    Abstract: An apparatus for equilibrating the temperature of the eluate of a separating column entering a flow cell includes the provision of a heat transfer relationship between the outlet fluid and the inlet conduit whereby the temperature of the fluid, as it passes through the flow cell, is stabilized.
    Type: Grant
    Filed: February 3, 1984
    Date of Patent: May 20, 1986
    Assignee: The Perkin-Elmer Corporation
    Inventor: Raymond P. W. Scott
  • Multifunctional detector
    Patent number: 4555936
    Abstract: A detector assembly includes means for determining the fluorescence characteristics, the ultraviolet absorbance characteristics and the electrical conductivity characteristics of a single sample of an eluate of a chromatographic separating column.
    Type: Grant
    Filed: December 13, 1984
    Date of Patent: December 3, 1985
    Assignee: The Perkin-Elmer Corporation
    Inventor: Raymond P. W. Scott
  • Apparatus useful in identifying a solute
    Patent number: 4476026
    Abstract: An apparatus useful in identifying a solute includes a microbore separation column having unusually large particle packing making up the bed thereof. In addition, the microbore column is excessively long compared to conventional columns. Preferably, the column is thermally stabilized.
    Type: Grant
