A flame photometric detector for a process gas chromatograph, the flame photometric detector comprising:
- a combustion chamber body defining a combustion chamber therein;
- a sample inlet tube configured to introduce a process gas sample into the combustion chamber;
- an ignitor configured to initiate combustion within the combustion chamber;
- a thermocouple assembly configured to provide an indication of temperature within the combustion chamber;
- wherein the sample inlet tube has an end that is adjustable relative to the combustion chamber;
- and
- a gas mixer threadably disposed within the combustion chamber body, and wherein rotation of the gas mixer affects the adjustable position of the end of the sample inlet tube relative to the combustion chamber.
A flame photometric detector for a process gas chromatograph, the flame photometric detector comprising:
- a combustion chamber body defining a combustion chamber therein;
- a sample inlet tube configured to introduce a process gas sample into the combustion chamber;
- an ignitor configured to initiate combustion within the combustion chamber;
- a thermocouple assembly configured to provide an indication of temperature within the combustion chamber;
- and
- wherein the combustion chamber includes a flat surface proximate an end of the sample inlet tube, a partially round surface having a zenith distal the flat surface, and a major are intersecting the zenith and contacting the flat surface.
