“…This paper also illustrates the feasibility of acoustic wave normalization in a flowing, atmospheric pressure ablation cell, as opposed to the static, low-pressure cells used previously (13,14). In future experiments, a cell with a very low dead volume, like those described by Carr and Horlick (20) and Tremblay et al (10), may be useful to maximize the transport efficiency and the time correlation between emission signal and acoustic signal. It will also be interesting to apply these normalization techniques to the more sensitive ICP-MS measurement and to determine whether acoustic normalization can be used for many different sample types to compensate for the usual lack of matrix-matched standards.…”

“…However, due to the low laser power density (104 W/cm2), metallic targets cannot be vaporized. A higher repetition rate (40-Hz) excimer laser was used to ablate sample into ICP (10); no precision measurement was reported.…”

Soon after the invention of the laser by Maiman, laser pulses were used for excitation and ionization of sample material for inorganic analysis by optical emission spectrometry (OES) or mass spectrometry (MS). This direct approach is complicated by the complexity of the laser–sample interaction and the need to optimize simultaneously the sampling and excitation (or ionization) steps. Use of a laser for solids sampling with separate atomization and excitation in an inductively coupled plasma (ICP) retains the advantages of direct solids analysis, including spatially resolved concentration data, and adds those attributable to the ICP, including wide elemental coverage, a linear dynamic range of six or more orders of magnitude, and excellent detection limits (DLs). The resulting techniques, denominated laser ablation/inductively coupled plasma/optical emission spectrometry (LA/ICP/OES) and laser ablation/inductively coupled plasma/mass spectrometry (LA/ICP/MS), are based on recording of relative emission intensities or ion count rates, respectively. Both methods are treated here, but emphasis is given to LA/ICP/MS, a rapidly developing technique in use for less than 15 years, which in addition to offering DLs typically 10 3 times lower than those obtained by LA/ICP/OES, also offers isotope ratio analysis. Hardware, analytical procedures, performance, and prospects are addressed. The power and limitations of the methods are illustrated by environmental applications, including the analysis of metals, soils, rocks, and plastics.
