Effects of acid type and concentration on the determination of 34 elements by simultaneous inductively coupled plasma atomic emission spectrometry

“…Most elements, however, were not acceptably linear from low concentrations to 1000 Mg/mL. These results agreed partially with those of Maessen and Balke (5), who found nonlinearity at low concentrations. The present results at low concentrations were found to be due to background effects and not to intrinsic nonlinearity.…”

“…Standard number 1 in Table IIA was replaced by 10% HC1. Optimization using the intensity mode and aspirating 10 gg/mL CdCl2 in 10% HC1 and 10% HC1 alone (4,5,20) for 10-s exposure times was then done (20). The optimum rf, torch height, argon pressure, and peristaltic pump flow rate were 1.20 kW, 16 mm above the top edge of the top of the plasma cooling coil, 29 psi, and 1.6 mL/min, respectively.…”

“…Few investigators have studied the effects of different acids on the chemical compatibility, interelemental interferences, and spectral background for a large number of elements when analyzed by inductively coupled plasma atomic emission spectrometry (ICP-AES). In contrast, there are many publications dealing with the effect of argon flow rate, rf power, and torch height (1)(2)(3)(4)(5), sample uptake (4, 5), and determination of interelemental interferences (6)(7)(8)(9).…”

Aerosol diagnostics and inductively coupled plasma mass spectrometry with demountable concentric nebulizers

“…8A), similar to conventional nebulizers. [38][39][40] High RF powers are required for optimal sensitivity (Fig. 8B), with the optimum being at 1400 W. The signal intensities of the test elements increase only by a factor ranging from 1.5 to 2 as the solution uptake rate is changed from 100 mL min 21 to mL min 21 , with no significant improvement beyond this level (Fig.…”

Comparison of Jarrell-Ash, Perkin-Elmer, and modified Perkin-Elmer nebulizers for inductively coupled plasma analysis

“…The objective of this investigation was to produce a nebulizer with performance characteristics equivalent to the Jarrell-Ash while retaining the ease of service of the Perkin-EImer unit. Although nebulizer efficiency has been cited as an evaluation criteria (1,5,7), the most widely accepted criteria appears to be detection limits based on three standard deviations of the blank readings (13). Two additional criteria were applied here: (1) the nebulizer must be capable of routine daily aspiration of urines or diluted sera, and (2) the nebulizer-plasma system must produce detection limits low enough to perform the intended analyses.…”
