Abstract: The cited system involves a specially designed purge cell to strip dissolved CO2 from solution into a H gas stream that serves as fuel for the hydrogen/air flame of the flame IR-emission (FIRE) radiometer. Sample stream is fed into the top of the cell through a PTFE tube and the H purge gas is supplied through a gas dispersion tube at the bottom of the cell. A side-arm links the cell to the FIRE burner and the spent analytical solution drains away through a bottom outlet. The system was applied in the process and FIA modes to the determination of total inorganic C in tap-water. In both modes the sample was mixed with 0.25 M HCl to release CO2. The procedure was extended to the determination of non-volatile organic materials by oxidizing the analytes to dissolved CO2 with peroxydisulfate in the presence of a Ag+ catalyst before purging. No details of detection limits or RSD are given.

Abstract: A review is presented of state-of-the-art FIA coupled to instruments capable of providing multidetection and/or multi-information. Tables are presented of the methods of FIA coupled with ICP-AES, ICP-MS, FTIR, MS, MECA, NMR and flame IR emission spectrometry with references. Interfaces, sample introduction, sample handling, online separation processes and speciation studies are discussed. (190 references).
