Comparison of LA-ICP-MS and LA-ICP-OES for the analysis of some elements in fly ashes

Abstract

International audienceIn this work quantitative analysis of minor and trace elements in fly ash by nanosecond laser ablation (LA)-ICP-MS and LA-ICP-OES was investigated in terms of detection limits and accuracy. Different binders and modifiers (silver or chromophores) were added to the fly ash powder to prepare mechanically stable pellets and improve sensitivity (signal to concentration ratio). Maleic acid was found to provide a higher degree of homogeneity between sensitivities across the different fly ashes tested. Ashes were from different origins: domestic waste incinerator or ashes from various coal-fired power plants. A calibration procedure using reference materials as standards was employed, the LAI-CP-MS analysis gave an acceptable accuracy (estimated from NIST 1633), better results were obtained using fused bead preparation. The use of the LA-ICP-OES system gave, when possible (higher concentrations), good results in terms of detection limits (1 to 11 mu g g(-1)) and accuracy

Simultaneous Determination of 11 Elements in Fly Ash by Inductively Coupled Plasma Orthogonal Acceleration Time-of-Flight Mass Spectrometry After Closed-Vessel Microwave-Assisted Extraction with Ammonium Fluoride

“…Inductively coupled plasma mass spectrometry has arisen as one of the preferred methods due to its unique combination of low detection limits, capabilities for rapid multi-elemental and isotopic determination and wide dynamic range [23]. Despite the significant improvements on solid sample introduction techniques such as laser ablation sampling [29] or slurry sampling electrothermal vaporization [30][31][32][33][34], solution nebulization is still the most preferred method for many ICP-MS applications [35].…”

Elemental analysis of coal by tandem laser induced breakdown spectroscopy and laser ablation inductively coupled plasma time of flight mass spectrometry

“…Van Heuzen et al [27] reported on about 50 elements determined by LA-ICP-MS after sample preparation based on mixing powdered coal with binder material. Stankova et al [28] utilized LA-ICP-MS to detect and quantify V, Cr, Mn, Ni, Cu, Zn, Sr, Ba, As and Pb in fly ashes. Rodushin et al [29] used solution nebulization and laser ablation for the multi- In this study we performed simultaneous determination and quantification of major and minor elements by LIBS, and trace elements using LA-TOF-ICP-MS. Univariate calibration and partial least squares regression (PLSR) were used for quantitative analysis of the coal composition (minor and trace elements).…”
