Hydride-generation atomic absorption spectrometry coupled with flow injection analysis
TL;DR: A flow injection technique was applied to hydride-generation atomic absorption spectrometry as discussed by the authors, where gas segmentation was found to be effective in minimizing the broadening of a sample zone without an increase of noise levels.

Trace metal enrichment by automated on-line column preconcentration for flow-injection atomic absorption spectrometry
TL;DR: An online column preconcentration technique for flow-injection atomic absorption spectrometry was developed in this paper, where diverse metal ions (Cd2+, Zn2+, Cu2+, Mn2+, Pb2+, Fe3+ and Cr3+) in solution were concentrated quantitatively by a microcolumn (7-mm × 4-mm id) packed with Muromac A-1, which is an iminodiacetate chelate resin, in a flowinjection system from the pH dependence of the uptake of the ions, all the divalent

Continuous separation techniques in flow injection analysis
TL;DR: In this paper, the similarities and differences between flow injection analysis (FIA) and high-performance liquid chromatography (HPLC) are discussed, and the objectives pursued with the formation of different types of interfaces in FIA are discussed: preconcentration, sample clean-up, etc.

TL;DR: The dispersion of sample zones in Flow Injection systems is described by analogy with the mixing of fluids in large-scale chemical reactors as mentioned in this paper, which has resulted in a definition of the sample zone dispersion, its mathematical description, and the identification of the main parameters which can be used to effect the desired degree of mixing.

Flow Injection Calibration Methods for Atomic Absorption Spectrometry
TL;DR: In this article, the use of an atomic absorption spectrometer as a detector in flow injection analysis is briefly reviewed, and a new simplified model is described for the dispersion effects observed with such systems; the model is based on considering dispersion to be due to a single hypothetical mixing chamber located immediately prior to the measurement stage.
