ABSTRACT:
An airflow director constructed for use with a separation column in a temperature-controlled air bath in a chromatographic oven cavity, wherein the airflow director includes at least a first baffle locatable with respect to the separation column and to the low pressure and high-pressure regions of the air bath, wherein the baffle is configured to direct air flow away from the high-pressure region before passing over the separation column. The temperature-controlled air thereby mixes with oven cavity air before passing over the separation column, which is thereby less subject to thermal gradients.
