Atomic spectroscopic detection
This chapter demonstrates the way in which the detection techniques can be exploited for on-line flow analysis, provided that they are cleverly interfaced with the flow manifolds. It focuses on the conceptual ways and means of exploiting flow systems for detection devices. The atomic spectroscopic-detection deals with (1) interfacing the flow network with the various atomic spectroscopic detectors, (2) flow systems as vehicles for on-line processing of liquid samples comprising solvent extraction, solid-phase extraction, bead injection, precipitation/ coprecipitation, gas–liquid separation, including hydride-generation (HG) and cold vapor (CV) generation and membrane-based separation, (3) flow systems as vehicles for on-line processing of solid samples encompassing fractionation and microwave/ultrasound extraction or digestion, and (4) hyphenated techniques with atomic spectroscopic detectors.
Liquid–liquid extraction is among the most effective sample pretreatment techniques in the separation of interfering species and preconcentration of metal or metalloid species. Hyphenation is required to subject the sample to appropriate pretreatments so that the detector used can identify the individual analyte species with suitable selectivity and sensitivity..
