Available in PDF, EPUB and Kindle. Book excerpt: A means of analyzing 99Tc in urine by inductively coupled plasma mass spectrometry (ICP-MS) has been developed. Historically, 99Tc analysis was based on the radiometric detection of the 293 keV E{sub Max} beta decay product by liquid scintillation or gas flow proportional counting. In a urine matrix, the analysis of99Tc is plagued with many difficulties using conventional radiometric methods. Difficulties originate during chemical separation due to the volatile nature of Tc2O-- or during radiation detection due to color or chemical quenching. A separation scheme for 99Tc detection by ICP-MS is given and is proven to be a sensitive and robust analytical alternative. A comparison of methods using radiometric and mass quantitation of 99Tc has been conducted in water, artificial urine, and real urine matrices at activity levels between 700 and 2,200 dpm/L. Liquid scintillation results based on an external standard quench correction and a quench curve correction method are compared to results obtained by ICP-MS. Each method produced accurate results, however the precision of the ICP-MS results is superior to that of liquid scintillation results. Limits of detection (LOD) for ICP-MS and liquid scintillation detection are 14.67 and 203.4 dpm/L, respectively, in a real urine matrix. In order to determine the basis for the increased precision of the ICP-MS results, the detection sensitivity for each method is derived and measured. The detection sensitivity for the 99Tc isotope by ICP-MS is 2.175 x 10−7 " 8.990 x 10−9 and by liquid scintillation is 7.434 x 10−14 " 7.461 x 10−15. A difference by seven orders of magnitude between the two detection systems allows ICP-MS samples to be analyzed for a period of 15 s compared to 3,600 s by liquid scintillation counting with a lower LOD.

Available in PDF, EPUB and Kindle. Book excerpt: With a level of detection of one part in 1015, inductively coupled plasma mass spectrometry (ICP-MS) is a highly sensitive tool in a huge range of analytical applications. Development of the technology continues rapidly, further opening up the scope for this invaluable analytical technique. Despite widespread interest and usage, little has been written to describe the analytical techniques and instrumentation in a format accessible to both new and experienced users of the technique. Inductively Coupled Plasma Mass Spectrometry Handbook provides a thorough description of ICP-MS instrumentation and techniques, giving the reader sufficient knowledge to approach the technique with confidence.

Available in PDF, EPUB and Kindle. Book excerpt: Since the introduction of the first commercial inductively coupled plasma mass spectrometry (ICP-MS) instruments in 1983, the technique has gained rapid and wide acceptance in many analytical laboratories. There are now well over 400 instruments installed worldwide, which are being used in a range of disciplines for the analysis of geological, environmental, water, medical, biological, metallurgical, nuclear and industrial samples. Experience oflCP-MS in many laboratories is limited, and there is therefore a need for a handbook containing practical advice in addition to fundamental informa tion. Such a handbook would be useful not only to users new to the technique, but also to users with some experience who wish to expand their knowledge of the subject. Therefore we have written this book for users in a variety of fields with differing levels of experience and expertise. The first two chapters provide a brief history of ICP-MS and discussions of design concepts, ICP physical processes, and fundamental principles of instrument operation. Armed with this background knowledge, users will be better equipped to evaluate advantages and limitations of the technique. Detailed descriptions and information for instrumental components are provided in chapter 3. Subsequent chapters deal with the practical aspects of sample analysis by ICP-MS. Whether samples are to be analysed in liquid, solid ·or gaseous form is always an important consideration, and there is a wide choice of sample introduction techniques.

This book was released on 2008-04-15 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of Inductively Coupled Plasma Spectrometry andits Applications was written as a handbook for users who wanted abetter understanding of the theory augmented by a practical insightof how best to approach a range of applications, and to provide auseful starting point for users trying an approach or technique newto them. These objectives have been retained in the second editionbut a slight shift in emphasis gives the volume an overallperspective that is more forward looking. Structured into 11 chapters, the current edition is a thoroughrevision of the original, covering the principles of inductivelycoupled plasmas, instrumentation, methodology and applicationswithin environmental analysis, earth science, food science andclinical medicine. Each chapter, written by internationallyrecognised leaders in their specific subject areas, provides enoughdetail to be useful to both the new and experienced users. Fullaccount is taken of recent developments, such as high resolutioninstruments, novel detection systems and electrospraytechniques. Written for all analytical scientists but particularly thoseinvolved in atomic spectroscopy and in environmental, geochemical,clinical or food analysis, this timely and informative book will bean essential reference in their use of inductively coupled plasmasto achieve their own scientific goals.

Available in PDF, EPUB and Kindle. Book excerpt: The Hazards Control Department at Lawrence Livermore National Laboratory (LLNL) uses Inductively Coupled Plasma Mass Spectrometer (ICP/MS) technology to analyze uranium in urine. The ICP/MS used by the Hazards Control Department is a Perkin-Elmer Elan 6000 ICP/MS. The Department of Energy Laboratory Accreditation Program requires that the total error be assessed for bioassay measurements. A previous evaluation of the errors associated with the ICP/MS measurement of uranium demonstrated a ± 9.6% error in the range of 0.01 to 0.02 [mu]g/l. However, the propagation of total error for concentrations above and below this level have heretofore been undetermined. This document is an evaluation of the errors associated with the current LLNL ICP/MS method for a more expanded range of uranium concentrations.
