  • Chromatography columns
    Patent number: 9034186
    Abstract: A chromatography column is prepared with a stationary phase comprising a deuterated poly(ethyleneglycol), or other deuterated polymer. Formation of the stationary phase can be performed using exactly the same methodology as used when forming a stationary phase with the equivalent non-deuterated polymer. The deuterated poly(ethyleneglycol), or other deuterated polymer, preferably has increased thermal stability as compared to non-deuterated poly(ethyleneglycol), or equivalent non-deuterated polymer. This reduces bleeding of the stationary phase during gas chromatography and allows the use of greater operating temperatures.
    Type: Grant
    Filed: January 19, 2006
    Date of Patent: May 19, 2015
    Assignee: Agilent Technologies, Inc.

  • Carrier for a chromatographic column
    Patent number: 6730216
    Abstract: An assembly consisting of a winding structure 1 around which a chromatographic column 6 can be wound, and an information carrier 7 which can be connected to said winding structure 1. This assembly offers a rigid and convenient means to handle one or two chromatographic columns of longer lengths. The information carrier 7 contains the chromatographic column identification information as well as several tools, such as a tool 13 to hold one or two chromatographic column connectors 11, a ruler to measure column insertion lengths and clips 12 to hold column ends, and clips to hold column extensions.
