Abstract
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.

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 sample inlet tube has an end that is adjustable relative to the combustion chamber.
A process gas chromatograph comprising:
- a temperature-controlled oven;
- at least one chromatographic column disposed within the temperature-controlled oven and being configured to receive a sample of process gas;
- a flame photometric detector operably coupled to the at least one chromatographic column and disposed within the temperature-controlled oven, the flame photometric detector being configured to combust the sample of process gas and provide an indication of a flame combusting the sample;
- and
- a photomultiplier tube assembly coupled to the flame photometric detector and configured to receive indication from the flame photometric detector and provide a signal indicative of a wavelength of the flame.
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 defines a combustion chamber therein, the combustion chamber having a half-round shape.
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 ignitor and the thermocouple assembly are mounted to a single tube that extends into the combustion chamber.
