“…The application of flow injection (FI) techniques to atomic spectroscopy in order to reduce interferences is well documented [11][12][13][14][15][16][17]. Several workers have applied FI to ICP-MS [5,7,[18][19][20][21].…”

Arsenic was determined in gold by flow injection hydride generation inductively coupled plasma-mass spectrometry follow ing a batch mode reductive precipitation removal of the interfering gold matrix. A solution of potassium iodide, L-ascorbic acid, and hydrochloric acid was used as the reluctant. The recovery of gold by precipitation and filtration was 99 ± 3%. The detection limit for arsenic in gold was 55 ng g-1 in the solid. The concentration of arsenic that was determined in the Royal Canadian Mint gold sample FAU-10 was 29.7 µ.g g-1 in the solid; this value was indistinguishable, with 95% confidence, from values determined at the Royal Canadian Mint by graphite furnace atomic absorption spectrometry and by inductively coupled plasma-mass spectrometry. The standard deviation for four replicate determinations of the arsenic in FAU-10 was 0.972 µ.g g-1 in the solid.

“…Closed loops also allow procedures which are typically slower than the operation of the spectrometer and slower than the typical reagent residence time in a conventional manifold to be implemented. Such procedures include leaching of analyte species from a solid sample (132) and filtration of a large amount of precipitated matrix (132). The general principle is illustrated in Fig.…”

“…The loop may be opened and closed by four-way valves and solutions can be inserted and removed by incorporating the loops of injection valves as part of the circulating loop. Such a loop system has some potential as a means of diluting off-range samples and the preparation of a series of calibration standards by serial dilution from a single concentrated stan dard (132).…”
