Abstract
Abstract The renewed interest in flame emission spectroscopy (FES) in recent years has lead a number of workers to investigate the potential of the mechanically separated or the gas sheathed flame as a low background, high temperature atom reservoir in analytical spectroscopy. The work reported so far has been reviewed elsewhere2,3, and will not be considered here, other than to indicate that only acetylene has been extensively investigated as a fuel for separated flames in FES. Separated hydrogen flames have been applied only to atomic fluorescence spectroscopy (AFS)4-6 particularly when non-dispersive detector systems have been used6. The object of the present investigation was to examine the potential application of the separation of some recently proposed flames7-11 in emission spectroscopy, including the nitrous oxide-hydrogen flame, the merits of which have recently been the subject of controversial discussion7,8, and the air and nitrous oxide MAPP Gas flames, which have been tentatively suggested9-...
