Atomic spectrometric detectors for flow-injection analysis

Determination of lead by hydride generation atom trapping flame atomic absorption spectrometry

“…[1][2][3] On-line preconcentration via retention of Pb within a certain pH on a micro-column of a solid support improves the sensitivity and selectivity. 4,5 Various procedures have been described for the determination of Pb by FAAS. [6][7][8][9][10][11][12][13][14][15] Most frequently, C 18 bonded silica gel sorbent [11][12][13][14][15] is used as the support material, while other adsorbents, including activated carbon, 16 alumina, 17 cellulose, 18 and Chromosorb 102, 19 have also been used.…”

Determination of As, Hg and Pb in herbs using slurry sampling flow injection chemical vapor generation inductively coupled plasma mass spectrometry

“…Additionally, it was also shown that appropriate vapor generation conditions can be used to remove or separate the analyte from problematic matrix species, which would otherwise cause spectral and nonspectral interferences (Chen & Jiang, 2006;Hwang & Jiang, 1997). Vapor introduction in flow injection mode is a simple and rapid technique that has been coupled to ICP-MS previously (Abranko et al, 2003;Huang, Jiang, & Hwang, 1995;Tyson, 1990). In the present investigation, a simple, laboratory-built vapor generation system is used as the sample introduction device for flow injection ICP-MS.…”

On‐line analyte preconcentration with atomic spectrometric detection

“…In addition to the papers detailing specific applications of FI and LC, there have been a number of authoritative reviews, for example on FI-ICP [80][81][82][83] and FI-atomic spectrometry [84][85][86]. A very comprehensive review of the literature is the second edition of Ruzicka and Hansen's book [87].…”
