Methods: XRF (major components and S, Sn, Ba, Sr, Rb, Nb, Zr, Y); ICP (Br, Ag, Ni, Co, Sc, Cu, Pb, Zn, Mo, Ga, Li); DCP (B, V, Ge, Be); NA (As, Sb, Cr, W, Cs, Ta, Hf, Th, U); AA (Cd, In); GFAA (Se); ICP (Au, Bi, Tl); ICP-MS (REE); wet chemical (FeO, [H.sub.2]O, Cl, Hg).
Here we present comparative data on ASV and GFAA analyses of blood lead in our clinic, with a novel reagent for calibration of ASV.
The application of automation has become most cost effective in GFAA; this technique can be very time consuming, and although it offers trace level capability (ug/L), it often suffers from chemical matrix effects.
Total arsenic concentration was measured by GFAA spectrometry using a PerkinElmer (Waltham, MA) AAnalyst 600 graphite furnace system with a detection limit of 2 pg/L, as previously described (Nixon et al.
Total uAs concentrations were measured by GFAA spectrometry using an Analyst 600 graphite furnace system (PerkinElmer, Shelton, CT) in the Columbia University Trace Metals Core Lab, as described previously (Nixon et al.
The pyro-coated graphite tubes and parts are designed for most GFAA spectrometers and have been designed to meet or exceed the specifications set by each original instrument manufacturer.
Total arsenic concentration was determined by graphite furnace atomic-absorption spectrometry (GFAA) with a Hitachi Z-8200 system (Hitachi Corp., Tokyo, Japan) (van Geen et al.
We used graphite furnace atomic absorption (GFAA), with a detection limit of 5 [micro]g/L, to measure total As in well-water samples.
Urinary As concentrations were assayed by graphite furnace atomic absorption spectrophotometry (GFAA) using a PerkinElmer AAnalyst 600 system (PerkinElmer, Shelton, CT, USA) as described (Nixon et al.
Total As concentrations were first determined by graphite furnace atomicabsorption spectrometry (GFAA) with a Hitachi Z-8200 system (Hitachi, Tokyo, Japan) at the Lamont-Doherty Earth observatory of CU (van Geen et al.
