A flame photometric detector for a process gas chromatograph is provided. The flame photometric detector includes a combustion chamber body defining a combustion chamber therein. A sample inlet tube is configured to introduce a process gas sample into the combustion chamber. An ignitor is configured to initiate combustion within the combustion chamber. A thermocouple assembly is configured to provide an indication of temperature within the combustion chamber. The sample tube has an end that is adjustable relative to the combustion chamber.

Flame photometric detector

A heating assembly includes a heater extending in a longitudinal direction from a first end to a second end. Heat transfer fins are thermally coupled to the heater and extend in a direction transverse to the longitudinal direction. An airflow component is positioned proximate one of the first and second end and is configured to generate airflow along the plurality of heat transfer fins toward the other of the first and second end.

Forced convection heater

A pneumatic multiport selector valve and analytic instrument employing said valve are provided. The valve includes a base having a mounting surface configured to mount to the analytic instrument. The mounting surface has a plurality of apertures therein for coupling to flow conduits of the analytic instrument. At least one piston plate has a number of apertures therethrough. The apertures are configured to slidably receive respective pistons. Pistons are disposed in respective apertures of the at least one piston plate. A cushion layer is disposed between the at least one piston plate and the base. The cushion layer has a plurality of apertures to allow actuation gas therethrough. A plate clamps the at least one piston plate to the base.
