“…A literature review reveals that different authors use the term 'fractionation' to describe related but subtly different phenomena [50][51][52][53][54] . In this dissertation, fractionation is a broad term for the processes by which elemental ratios of a solid sample are determined inaccurately by LA-ICP-MS.…”

“…Si (I), Si (II), and SiO have little emission in the visible spectrum [51][52][53] . The observed emission in the outer edge of the IRZ is attributed to a weak neutral silicon emission line at 390 nm or a stronger emission line at 288 nm.…”

“…However, because ICP-MS may be more affected by sample matrix effects such as 155 those typically encountered with surface wipes, this technique may not be as good a choice for analysis of surface wipes as ICP-AES. On the other hand, ICP-AES is subject to spectral interferences with all three of the primary lines used for beryllium (see Table 2) 32,33 Once samples are collected on air filters or surface wipes, the 175 beryllium is brought into solution, by digestion or extraction, prior to instrumental analysis. The ICP-AES, ICP-MS, and AAS methods rely on sample preaparation by an acid digestion involving one or more acids in combination with heat.…”

“…Most of the matrix effects are caused by the easily ionizable elements (EIEs) 22,23 . Anyway, several spectral interferences have been found in the determination of As and Pb by ICP-OES 24 . Direct spectral overlap interference due to Fe was found when Pb was determined in the emission 70 lines 217.000 nm and 283.306 nm 24,25 .…”

A multiple linear regression technique was used to evaluate and correct the matrix interferences in the determination of As and Pb concentrations in fly ashes by inductively coupled plasma optical emission spectrometry. The direct determination of As and Pb in SRM 1633b by ICP-OES failed to obtain the certified concentrations, except in a couple of cases. However, it proved possible to use the multiple linear regression (MLR) technique to correct the determined concentrations to a satisfactory level. This method of correction is based on the multiple regression line obtained from the analysis of 19 synthetic mixtures of matrix and analyte elements (Al, As, Ca, Fe, Pb, and Si) at five concentration levels. The matrix interferences in the determination of As were caused by Al, Pb, and Ca whereas the matrix interferences in the determination of Pb were caused by Al and Fe. The most suitable parameters for the determination of As and Pb were a plasma power of 1500 W and a nebulizer flow of 0.5 or 0.6 L min À1 . The accuracy of the method was shown with the analysis of SRM 1633b and two fly ash samples with the standard addition method. A recovery rate of 96% can be reached for Pb at 220.353 nm with three digestion methods (US-TSD, US1 and MW) by using both direct measurement with thoroughly optimized plasma conditions and the MLR method. A recovery rate of 93% was obtained for As when using the MLR method at 193.696 nm with the digestion method US2, a plasma power of 1500 W, and nebulizer flow of 0.6 L min À1 . The corrected and determined concentrations of As and Pb in samples analyzed resulted in a precision of 0.6 to 3.9%.
