Abstract
A system for performing gas chromatography analyses in accordance with the present disclosure includes an analytical column and a column oven. The analytical column has an inlet portion coupled to an injector for receiving a material sample and an outlet portion coupled to a detector. The analytical column is adapted to direct the material sample from the injector to the detector. The column oven is adapted to heat the analytical column for separating constituent components of the material sample for detection by the detector.
Claims18
A system for performing gas chromatography analyses, the system comprising:
- an analytical column having an inlet portion coupled to an injector for receiving a material sample and an outlet portion coupled to a detector, the analytical column adapted to direct the material sample from the injector to the detector;
- an inlet heater coupled to the inlet portion of the analytical column and configured to produce one or more heat zones along the inlet portion of the analytical column;
- an outlet heater coupled to the outlet portion of the analytical column and configured to produce one or more heat zones along the outlet portion of the analytical column;
- and
- a controller operatively coupled to the inlet heater and the outlet heater,
- wherein the controller is configured to selectively power the inlet heater and the outlet heater to define a steady-state temperature profile along the analytical column.
A system for performing gas chromatography analyses, the system comprising:
- an analytical column having an inlet portion coupled to an injector for receiving a material sample and an outlet portion coupled to a detector, the analytical column adapted to direct the material sample from the injector to the detector;
- an inlet heater coupled to the inlet portion of the analytical column and configured to produce one or more heat zones along the inlet portion of the analytical column;
- an outlet heater coupled to the outlet portion of the analytical column and configured to produce one or more heat zones along the outlet portion of the analytical column;
- and
- a controller operatively coupled to the inlet heater and the outlet heater,
- wherein the controller is configured to selectively power the inlet heater and the outlet heater to define a steady-state temperature profile along the analytical column, and the temperature profile has at least a first temperature gradient and a second temperature gradient.
A fluidless column oven for use in a gas chromatography system, the fluidless column oven comprising:
- a support frame;
- an inlet heater coupled to a first portion of the support frame;
- and
- an outlet heater coupled to a second portion of the support frame different than the first portion,
- wherein the inlet heater is configured to produce one or more heat zones and the outlet heater is configured to produce one or more heat zones, and the one or more heat zones produced by the inlet heater together with the one or more heat zones produced by the outlet heater define a steady-state temperature profile along the support frame.
A system for performing gas chromatography analyses, the system comprising:
- a column assembly including:
- a column support frame;
- and
- an analytical column coupled to the column support frame, the analytical column having an inlet portion coupled to an injector for receiving a material sample and an outlet portion coupled to a detector, the analytical column adapted to direct the material sample from the injector to the detector;
- a fluidless column oven including:
- a heater support frame;
- an inlet heater coupled to the heater support frame adjacent to the inlet portion of the analytical column, the inlet heater configured to produce one or more heat zones along the inlet portion of the analytical column;
- an outlet heater coupled to the heater support frame adjacent to the outlet portion of the analytical column, the outlet heater configured to produce one or more heat zones along the outlet portion of the analytical column;
- and
- a controller operatively coupled to the inlet heater and the outlet heater,
- wherein the fluidless column oven is configured to be received in the column assembly for heating of the analytical column, and the controller is configured to selectively power the inlet heater and the outlet heater to define a steady-state temperature profile along the analytical column.
