  • Separation column for a gas chromatograph
    Patent number: 6607580
    Abstract: A separation column for a gas chromatograph that includes a block of electrically insulating material having a channel located between two strips of thermoelectric material spaced from the channel by strips of electrically insulating material. Electrodes are connected to opposite ends of the strips of thermoelectric material. More specifically, each strip of thermoelectric material has two layers of dissimilar material to enable the strips to provide selective heating and cooling depending on the direction of current flow through the strips.
