Title

FPD: Burner Configurations and the Response to Hetero-organics

Abstract

Dependence of flame photometric detector response on burner design and other parameters, such as flow rates of H2, O2, air, and mode of mixing was investigated. These parameters affected the response of sulfur, phosphorus, and arsenic test compounds to a varying degree. Addition of helium to the flame caused an enhancement in sulfur and phosphorus response, and a 3-fold increase in S/N ratio was obtained. With optimized conditions, a minimum detectable limit of about 3 pg methyl parathion was obtained. Under suitable conditions good sensitivity and selectivity (over carbon) were observed for triphenyl arsine.
