Abstract: Abstract of thesis entitled DEVELOPMENT AND CHARACTERIZATION OF A NEW LASER ABLATION TECHNIQUE FOR INDUCTIVELY COUPLED PLASMA - ATOMIC EMISSION SPECTROMETRY (ICP-AES) submitted by LAMKARKIN for the degree of Master of Philosophy at The University of Hong Kong in March 1996 A novel laser sampling technique, back surface ablation, has been developed for inductively coupled plasma - atomic emission spectrometry (ICP-AES). Samples are coated onto a transparent substrate and a laser beam is irradiated onto the sample through the substrate instead of sampling directly from a sample surface. As part of the sample is vaporized by the laser beam, high pressure develops at the sample-substrate interface. The sample at the laser spot is explosively and completely removed by the expanding vapor. Sampling efficiency is up to 10 times higher than conventional "front surface" laser sampling. Also, stoichiometric sampling is ensured because of complete removal of the sample at the laser spot. The risk of inaccurate chemical analysis associated with non- stoichiometric thermal vaporization in front surface laser sampling is reduced. Two methods of calibration, standard additions and calibration with standards in poly(vinyl alcohol) matrix, were used for quantitative analysis of household paints usingfront surface and back surface ablation-ICP-AES. Internal standards are used to compensate for pulse-to-pulse laser energy fluctuation and sample thickness variation across a sample. Twelve elements of different thermal properties and concentration ranging from 1 ppm to 2000 ppm were analyzed and the elemental concentration was compared to that of microwave digestion/solution nebulization-ICP-AES. Back surface ablation appears to be more precise and accurate than conventional front surface ablation. DOI: 10.5353/th_b3025281 Subjects: Laser ablation Atomic emission spectroscopy
Download or read book Initial Report on the Application of Laser Ablation Inductively Coupled Plasma Mass Spectrometry for the Analysis of Radioactive Hanford Tank Waste Materials written by and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Initial LA/MS analyses of Hanford tank waste samples were performed successfully using laboratory and hot cell LA/MS instrumentation systems. The experiments described in this report have demonstrated that the LA/MS data can be used to provide rapid analysis of solid, radioactive Hanford tank waste samples to identify major, minor, and trace constituents (elemental and isotopic) and fission products and radioactive isotopes. The ability to determine isotopic constituents using the LA/MS method yielded significant advantages over ICP/AES analysis by providing valuable information on fission products and radioactive constituents.

This book was released on 2001 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigate particles produced by laser irradiation and their analysis by Laser Ablation Inductively Coupled Plasma Mass Spectroscopy (LA/ICP-MS), with a view towards optimizing particle production for analysis of high level waste materials and waste glass. LA/ICP-MS has considerable potential to increase the safety and speed of analysis required for the remediation of high level wastes from cold war plutonium production operations. In some sample types, notably the sodium nitrate-based wastes at Hanford and elsewhere, chemical analysis using typical laser conditions depends strongly on the details of sample history composition in a complex fashion, rendering the results of analysis uncertain. Conversely, waste glass materials appear to be better behaved and require different strategies to optimize analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Laser ablation refers to the phenomenon in which an intense laser beam irradiates the surface of a solid to induce instant local removal of atoms by a thermal or non-thermal mechanism. Through eight chapters of original research studies and literature reviews written by experts from the international scientific community, this book presents theoretical and experimental aspects of the laser ablation phenomenon for processing material including pulsed laser deposition of thin films, laser surface modification, laser machining and laser nanoparticle formation. It also includes a study of the dynamics of plasmas generated by laser ablation of multi-component materials and an overview of laser-induced breakdown spectroscopy (LIBS) and laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) techniques for chemical analysis.

This book was released on 1998 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors goal is to provide fundamental mechanistic studies of laser produced particulate formation in support of the use of Laser Assisted-Inductively Coupled Plasma-Mass Spectroscopy (LA-ICP-MS) to be used for analysis of radioactive/toxic materials. The work reported here represents the first nine months of this 3-year project. The major focus of these studies is determining the detailed mechanisms and character of the particulates generated by laser ablation of solid targets relevant to sampling materials for chemical analysis using inductively coupled mass spectroscopy, ICP-MS. In this application, particles generated by laser ablation must be transported to the plasma torch of the ICP-MS, often through a hollow tube with an interior diameter of a few mm. Proper digestion and ionization of particles in the plasma limits particle sizes to under a micron. Thus the production of submicron particles which truly represent the stoichiometry of the specimen is of critical importance.
