摘要：

A commercial flame photometric detector was modified such that a larger fraction of its luminescence would reach the photomultiplier tube. As tested with compounds of lead and osmium, these modifications resulted in up to fifty times enhanced light transmissions and -in rough accordance with the square-root dependence of quantum noise- typically sevenfold improvements in signal-to-noise ratio.
