Abstract
A system and method for tuning a pulsed-flame photometric detector including providing a carrier gas within a predetermined gas flow range to the pulsed-flame photometric detector, providing at least one combustible fuel to the pulsed-flame photometric detector, applying voltage to an igniter coil associated with the pulsed-flame photometric detector, verifying that the pulsed-flame photometric detector is pulsing above a lower predetermined frequency and above a higher predetermined frequency, adjusting the gas flow of the at least one combustible fuel to the pulsed-flame photometric detector so that at least one cycle of ignition, propagation and then termination is present, heating a container to a predetermined temperature, allowing the at least one carrier gas to flow within the container, housing a tuning compound, and monitoring a width of a sulfur emission resulting from the combustion of the tuning compound to evaluate the width of sulfur emission signal all through a controller.
