Molecular absorption and light scattering in flames employed for atomic absorption spectroscopy

Abstract

The amount of analyte in solution (pg/ml) which absorbs the same amount of the resonance line as the given concentration of interférant.

An experimental and theoretical evaluation of the nitrous oxide-acetylene flame as an atomization cell for flame spectroscopy

“…The gas flow metering system is shown in Figure 2 and is consistent with the suggestions of Veillon and Park (64). Further constructional details may be found in (65). Each rotameter was calibrated at the desired pressure, with a precision wet test meter (Precision Temperature measurements were performed by the Sr linereversal technique described previously (25).…”

“…Flow monitoring systemScientific). The accuracy to which the flow ratio of N^O to CgHg (p) could be determined was ^ 1 or 2%.The burner, which was designed(46) and modified(65) by Fiorino, provided a premixed laminar flow flame with an optical absorbing path of 7.6 cm. The burner port was not water cooled.…”
