Flow Injection Analysis Techniques of Method Development for Flame Atomic Absorption Spectrometry
Analyst
(1985)
Abstract
The flow injection introduction of samples that would be difficult by conventional nebulisation owing to
dissolved solid content, viscosity or quenching effects on flame reactions is demonstrated. The various ways
of achieving sample dilution by control of volume injected, tube dimensions and flow-rate are discussed and a
manifold described for producing solutions for calibration purposes and diluting off-range samples. The
important characteristics of the nebuliser and instrument for flow injection work are evaluated. A simple
manifold for investigating interference effects is described and its use illustrated for some well known effects.
The possibilities of achieving pre-treatment by solvent extraction and extension to include indirect methods
are discussed and the role of flow injection procedures in the method development for, and the extension of
the range of application of, flame atomic-absorption spectrometry is critically evaluated.
