Abstract

A gas chromatography (GC) column heating apparatus is described. The GC column heating apparatus includes a first substrate; a heating element disposed over the first substrate; and a second substrate. A gas chromatography (GC) column heating and cooling apparatus is also described. The GC column cooling and heating apparatus includes a housing configured to receive a heating apparatus, the heating apparatus comprising a first side and a second side; a first thermal insulation layer disposed over the first side; a second thermal insulation layer disposed over the second side; and an actuator connected to the housing and configured to move the first and second thermal insulation layers in contact with the first and second sides, respectively, during a heating sequence, and to move the first and second layers of insulation out of contact with the first and second sides, respectively, during a cooling sequence.
