Abstract
A temperature controlled oven chamber for gas chromatography incorporates a first stationary chamber wall, a second stationary chamber wall arranged remote from the first wall, and a displaceable chamber wall which is moveable between a closed position and an open position. In the closed position, the displaceable chamber wall forms the casing of the chamber or housing, and surrounds stationary analytical devices. In the open position, the displaceable wall is moved away from the first stationary wall, thereby opening the chamber or housing and yielding access to the analytical devices. When moving from the closed position to the open position, the displaceable wall will enclose the second wall at least temporarily.
Claims15
A temperature controlled oven chamber for gas chromatography, said chamber containing stationary analytical devices including a chromatographic column, an air circulating device and a heating device for maintaining said column at a desired temperature, the improvement comprising, in combination:
- (a) first stationary chamber wall means;
- (b) second stationary chamber wall means arranged remote from said first wall means;
- and
- (c) displaceable chamber wall means moveable between
- (.alpha.) a closed position, in which said displaceable wall means are in contact with said first and second stationary wall means, thereby closing said oven chamber and insulating said analtyical devices from the outside;
- and
- (.beta.) an open position, in which said displaceable wall means are remote from said first wall means and shifted towards said second wall means, thereby opening said chamber for access to said analytical devices,
- said displaceable wall means enclosing said second wall means at least temporarily when moving from said closed position to said open position.
A temperature controlled oven chamber for gas chromatography, said chamber containing stationary analytical devices including a chromatographic column, an air circulating device and a heating device for maintaining said column at a desired temperature, said chamber having first and second stationary end walls, said second end wall being substantially parallel to said first end wall, and side walls extending between said end walls, said side walls being slideably moveable longitudinally and axially of said chamber from a heat sealing closed position to an open position, exposing in said open position the interior of said chamber from a front and at least two opposite sides.
