GAS CHROMATOGRAPHY OVEN AND SYSTEMS AND METHODS INCLUDING SAME

摘要

A gas chromatography system includes a gas chromatography oven and a gas chromatography column. The gas chromatography oven includes a housing and a flow generating system. The housing defines an oven chamber and an intake port fluidly communicating with the oven chamber. The fluid flow generating system includes a radial flow impeller. The gas chromatography column is disposed in the oven chamber. The oven is configured to selectively operate in each of: a cooling mode wherein the radial flow impeller generates a cooling fluid flow that is drawn from the intake port and flows about the column and out of the oven chamber; and alternatively, a recirculating mode wherein the radial flow impeller generates a recirculating fluid flow within the oven chamber that repeatedly flows about the column and back to the radial flow impeller.
