“…Kirkbright, Semb, and West (307) devised a separated air-acetylene flame as an emission source, the advantage being that it is possible to observe spectra only from the interconal zone, where the background emission is relatively low. Relatively low background intensities also led Skogerboe, Heybey, and Morrison (556) to reinvestigate the hydrogen-oxygen flame as an emission source, and they measured sensitivities and detection limits for some 25 elements which, because they form stable oxides, are most frequently determined with fuel-rich acetylene flames. Burner designs giving broader flames for atomic absorption spectrometry were developed by Boling (55) and Butler (84)', the broader flames were claimed to provide improved sensitivity and precision.…”
