By using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), the measurement of particle size has been made for one component oxide (Al 2 O 3 and MgO) and multicomponent oxide (12CaO · 7Al 2 O 3 and CaO-Al 2 O 3 -MgO) located on surface of iron or glass sample. The method of particle size estimation by LA-ICP-MS has been developed coupled with a new method of making samples with particles. The size calibration lines for Al 2 O 3 , MgO and CaO particles have been obtained. The results of particle size measurement by LA-ICP-MS are compared with those by SEM and single-particle optical sensing (SPOS) methods. It was confirmed that LA-ICP-MS has the perspective to be used for the quick measurement of inclusion composition and size in metal and other materials. The size frequency distributions of Al 2 O 3 particles measured by LA-ICP-MS in iron samples with particles agree reasonably well with those by SEM and SPOS in the range of particle diameter from 2 to 20 mm. The size of Al 2 O 3 , MgO and complex oxide (12CaO · 7Al 2 O 3 and CaO-Al 2 O 3 -MgO) particles measured by LA-ICP-MS is in good agreement with that by SEM in the range of particle diameter from 10 to 40 mm.KEY WORDS: quantitative analysis; metal; particle size; laser ablation ICP mass spectrometry.

“…For these reasons, direct methods for the analysis of solid samples are very attractive in ICP-MS analysis. [6][7][8][9][10][11][12] A new technique for introduction of aqueous suspensions of finely powdered solids, termed slurry nebulization, has been successfully applied to the direct ICP emission spectrometric analysis of powder materials of geochemical and environmental origins.13-" Slurry nebulization offers unique advantages over other types of solid sample introduction methods such as laser ablation or spark nebulization, because it can be calibrated with simple aqueous standards and requires a minimum modification of conventional instrumentation.…”

Direct analysis of silicate samples for the rare earth elements (REEs) by inductively coupled plasma mass spectrometry (ICP-MS) has been performed. Each finely ground sample (particle size <3 µm) was dispersed in 0.1% aqueous Triton X-100 solution and nebulized into an inductively coupled plasma. The resulting ions were detected by mass spectrometry. Parameters such as particle size, slurry concentration and argon carrier flow rate exercised a great influence on sensitivity, precision and accuracy of slurry nebulization/ICP-MS. Calibration curves were constructed using aqueous standard solutions. The extended dynamic range (EDR) detection system allowed the use of matrix element as an internal standard; this procedure was effective to correct the differences in sensitivity between the solution and the slurry methods. The optimum procedure was applied to the determination of REEs in standard silicate rocks of the Geological Survey of Japan. The precision ranged from 0.8 to 6.3 (RSD, %) for REEs contents of 0.13 -38 ppm. Detection limits of REEs were excellent (0.002 -0.02 ppm at the effective integrating time of 10 s). KeywordsSlurry nebulization, inductively elements coupled plasma mass spectrometry, silicate analysis, rare earthInductively coupled plasma (ICP) is now becoming accepted as an effective ionization source for subsequent mass spectrometric measurement. Comprehensive reviews have been presented by Date', Houk2 and Kawaguchi.3 In initial works on ICP mass spectrometry (ICP-MS), samples were generally introduced into ICP as aerosols of aqueous solutions; therefore, the dissolution of solid samples was required for many applications. This process is quite labor-intensive and time-consuming, especially for the analysis of refractory ceramic or silicate rocks.

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.
