ABSTRACT:
Energy efficiency of a thermal zone in an analytical instrument is improved by use of an oven cavity insert that may be removably positioned in an insulated enclosure in an oven cavity housing, whereby the combination of the oven cavity insert and one or more of the enclosure walls completely encloses a first space suitable for effecting the thermal zone. The oven cavity insert is positionable so as to separate the first space from at least a portion of the unused volume of the oven cavity, thus reducing the volume of the thermal zone, so as to reduce the amount of heating or cooling required for temperature control of a component positioned therein. When present in the oven cavity, the contemplated oven cavity insert effectively conceals a portion of the housing from the thermal zone, thus reducing the effective thermal mass of the oven cavity housing.
