“…15 The on-line coupling of FI-ETAAS has been proved to be a powerful technique for trace determination of a variety of elements. [13][14][15][16][17][18][19] Microdialysis, shown to be a powerful technique for in vivo systems, is a continuous sampling method. Microdialysates are collected over a fixed time interval to provide the required sample volume, and each sample represents an average concentration value obtained over this time interval.…”

“…Due to these advantages, microwaves have been used on-line in different studies for the determination of trace metals. [9][10][11] However, these systems present some drawbacks such as matrix interferences (because the sample matrix is introduced into the detector) and the need of a cooling area in the FI system (due to the high temperature of the microwave oven). Ultrasound-assisted extraction is another way of converting the analyte to a liquid phase.…”

“…Total As was determined after reduction of AsV (with KI and ascorbic acid), and hence AsV was (98 references) by the Burgueras. 121 Welz has reviewed219 the possibilities of solid-phase extraction and ETAAS for the determined by difference. Bulska and Jedral228 determined Pb in high purity reagents after electrolytic preconcentration on a particular field of the trace element analysis of body fluids.…”
