| Abstract |
A prototype flame photometric detector system (FPD) to measure gaseous sulfur compounds was fabricated using a previously developed correlation mask optical system and a new flame housing. Also, a new burner for the FPD system was optimized to view the excited molecular sulfur emission. The sample/hydrogen intake system was also redesigned to operate under a positive pressure, resulting in improved flame stability. The prototype detector system was equipped with a cooled photomultiplier with special optics to enhance sensitivity. Initial tests with the completed system indicated the capability of measuring sulfur dioxide at the part-per-billion level. Because of subsequent problems, an absolute calibration of the system was not carried out. |
