A fluid coupling comprises a compliant material, a seal gland having at least one projection configured to contact the compliant material, and a cover plate configured to compress the compliant material into the gland, thus forcing the compliant material against the projection.

Fluid coupling for a chromatograph

A radiant oven comprises a radiant energy source configured to provide radiant electromagnetic energy, an insert configured to receive the radiant electromagnetic energy and convert the radiant electromagnetic energy into heat, and an additional element configured to receive the heat.

Gas chromatograph having a radiant oven for analytical devices

An apparatus, system and method reduce the cool down time of GC ovens by supplying larger volumes of air through oven intake ducts. The system and method provide intake cross-sheets in an oven intake duct to reduce airflow spin, increasing the flow rate of fresh air into the GC oven and reducing the overall cool-down time of the GC oven. In addition, because the improved airflow allows the oven wall temperature to quickly match the oven air temperature, the noise in the temperature signal may be reduced. As a result, the GC oven can reach an equilibrium 'ready' state faster. Furthermore, the utilization of the cross-sheets may allow for flexibility in the design of a fast GC oven&#x2014;specifically in the location and shape of the intake duct&#x2014;without loss of performance. This flexibility may become increasingly significant as GC ovens continue on the trend of becoming smaller and faster.

Intake cross-sheets for gas chromatographic oven

An inward opening oven intake for a gas chromatographic (GC) oven includes an inward opening intake flap that opens into the GC oven near the bottom of the GC oven. Opening at a flap angle, the inward opening intake flap creates a low-pressure region to draw a large amount of airflow into the GC oven during cool-down. In addition, the inward opening oven intake manipulates the airflow within the GC oven to more efficiently draw heat away from the oven walls. This greater efficiency allows for faster cycle time and higher sample throughput.
