“…The resulting continuum emission can be resolved both spectrally and temporally to yield spectra containing the atomic emission lines corresponding to the atoms present in the plasma volume. The origin and uses of the LIBS technique have been summarized in several ( publications Cremers and Radziemski ) 1987;Laqua 1979 , and there are reviews of a wide range of LIBS studies available in ( the literature Radziemski and Cremers 1989;Darke and Tyson 1993;Radziemski 1994;Rusak et al 1997;Schechter 1997; ) Song et al 1997 .

( ) ABSTRACT. Laser-induced breakdown spectroscopy LIBS was evaluated as a means for quantitative analysis of the size, mass, and composition of individual micron-to submicron-sized aerosol particles over a range of well-characterized experimental conditions. Conditional data analysis was used to identify LIBS spectra that correspond to discrete aerosol particles under low aerosol particle loadings. The size distributions of monodisperse particle source ows were measured us ing the LIBS technique for calcium-and magnesium-based aerosols. The resulting size distributions were in good agreement with independently measured size distribution data. A lower size detection limit of 175 nm was determined for the calcium-and magnesium-based particles, which corresponds to a detectable mass of approximately 3 femtograms. In addition, the accuracy of the LIBS technique for the interference-free analysis of different particle types was veri ed us ing a binary aerosol system of calcium-based and chromium particles.

Characterisation of Inclusions in Clean Steels via Laser Ablation-ICP Mass Spectrometry

A new method for detection and assessment of inclusions in clean steels based on laser ablation and ICP mass spectrometry has been developed. Samples were subjected to UV laser ablation (Nd Yag) and ion intensities of elements of interest were monitored on a time-resolved basis. Lasers exhibiting both gaussian and flat-top intensity beam distributions were used. Analytical response for inclusion and matrix elements as a function of laser ablation parameters was studied and procedures were developed for rapid inclusion characterisation and elemental mapping. Main inclusion types identified in clean steels were Mn-S, Mg-Al and Mg-Al-Ca-Ti-Si. Results indicate the considerable analytical potential for the laser ablation technique in a production environment.KEY WORDS: clean steels; inclusions; mapping laser ablation; ICP mass spectrometry.a versatile microanalytical technique and is analogous to the SSE method in that elemental analysis is based on direct spectral observation of the plasma discharge. LIBS has yet to be fully exploited for characterisation of inclusions in clean steels but the potential is considerable given its success as a microanalytical tool [8][9][10][11] for spatially resolved measurement and depth profiling. 10,[12][13][14] Progress in the use of LIBS for inclusion measurement has recently been elaborated by Noll et al. 15) and Laserna et al. 16)Laser ablation in combination with ICP emission or ICP mass spectrometry constitutes an important bulk and microanalysis tool as evidenced by an extensive literature.

[23][24][25] The aim of this research was to evaluate the potential of the LA-ICP-MS method for steel cleanness assessment. The effects of key parameters, i.e. laser energy, frequency, spot size, and rate of sample translation on signal response have been investigated using both gaussian and flat top beam intensity distribution profiles. The approach permits rapid identification of elements present in inclusions and gives new information related to the spatial distribution of inclusions in samples. Experimental MaterialsA glass standard reference material (SRM 612, NIST, Gaithersburg, MD) was used for initial instrument set-up (daily basis) and in-house research materials previously characterised by optical metallography were used in method development. InstrumentationLaser ablation was performed using Nd Yag lasers (LSX-100 and LSX-200, frequency quadrupoled; CETAC Technologies, Omaha) interfaced to an ICP mass spectrometer (Agilent Technologies, HP 4500). The main difference in the two laser systems was that the LSX-100 exhibits a gaussian ...

“…GD is best suited for conductive samples, although nonconductive samples can be analyzed with a radiofrequency discharge. A GD source coupled to a high-resolution mass spectrometer is a powerful technique for achieving excellent depth profiling and detection characteristics with a limit of detection (LOD) in the range 10 -100 ng g 1 . For arc/spark ablation, mass is eroded from the sample in the form of atoms, molecules, vapor, droplets, solid flakes, and large particles.…”

Laser ablation (LA) is a unique technique to transform a solid sample into vapor‐phase constituents, which then can be chemically analyzed by atomic spectroscopy. Ablation brings many exciting capabilities to the field of chemical analysis, primarily because of the laser‐beam properties. The ability to analyze directly any solid samplewithout sample preparation and minimal sample‐quantity requirements are just some of the unique capabilities. This article discusses current issues related to using LA in atomic spectroscopy. A general introduction to LA sampling is presented along with a comparison with other solid sampling techniques. The critical issues for all analytical techniques are calibration, accuracy, and sensitivity. Techniques that have been demonstrated to address these analytical characteristics and define these parameters for LA are investigated in detail. Finally, many unique applications are described, ranging from dating geological materials to providing crime‐scene evidence. Most of these applications could not be performed without the use of a laser beam. The inductively coupled plasma (ICP) will be emphasized in this article because it is currently the most prevalent excitation and ionization source for chemical analysis using LA.
