Abstract
A column oven includes a substantially sealed space surrounded by wall surfaces made of a heat conductive material to accommodate an analytical column, a heater for heating the wall surfaces made of the heat conductive material, and a heat insulating material surrounding an outside of the wall surfaces made of the heat conductive material. That is, a space inside the column oven in which the analytical column is accommodated is formed as a substantially sealed structure surrounded by the heat conductive wall surfaces, and the wall surfaces surrounding the substantially sealed space are heated by the heater, thereby heating the substantially sealed space uniformly from circumferential directions.
Claims7
A column oven comprising:
- a substantially sealed space surrounded by wall surfaces made of a heat conductive material to accommodate an analytical column, all of the wall surfaces made of the heat conductive material coming into contact with each other;
- a column holder provided in the substantially sealed space while being in thermal contact with one wall surface of the wall surfaces and configured to hold the analytical column by being in thermal contact with the analytical column, and a whole of the column holder being made of a heat conductive material,
- a heater for heating the wall surfaces made of the heat conductive material while coming into contact with the wall surfaces;
- and
- a heat insulating material surrounding an outside of the wall surfaces made of the heat conductive material, wherein
- the column oven is configured so that heat of the heater is transferred to all of the wall surfaces surrounding the substantially sealed space, and
- the column holder has a rectangular shape, a longitudinal direction, and a recess along to the longitudinal direction, and the column holder holds the analytical column in the recess.
