This book was released on 2005 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forensic analysis of glass samples was performed in different laboratories within the NITE-CRIME (Natural Isotopes and Trace Elements in Criminalistics and Environmental Forensics) European Network, using a variety of Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) systems. The main objective of the interlaboratory tests was to cross-validate the different combinations of laser ablation systems with different ICP-MS instruments. A first study using widely available samples, such as the NIST SRM 610 and NIST SRM 612 reference glasses, led to deviations in the determined concentrations for trace elements amongst the laboratories up to 60%. Extensive discussion among the laboratories and the production of new glass reference standards (FGS 1 and FGS 2) established an improved analytical protocol, which was tested on a well-characterized float glass sample (FG 10-1 from the BKA Wiesbaden collection) Subsequently, interlaboratory tests produced improved results for nearly all elements with a deviation of

Download or read book Non destructive Elemental Analysis written by Zeev B. Alfassi and published by Wiley-Blackwell. This book was released on 2001-07-09 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is written for professional, academic and government analytical chemists. It is a "one-stop-shop" providing an overview and reference source on this subject, which has been growing steadily with outstanding technical developments in recent years. Non-destructive methods are generally nuclear techniques as they depend only on physical properties of the atomic nucleus and do not need the preparation of solutions. However some of the methods as XRF and ICP-MS-LA which depend on the inner electrons or the mass of the atom are also included as they are non-destructive. Non-destructive assays are expanding in the fields of materials, archaeology, biology and the arts. A team of expert authors describes all the major non-destructive methods available to the analyst clearly and concisely. In each case practical examples are used along with detailed coverage of equipment, methodology and underlying theory. In this way readers can gain an appreciation of how day-to-day work is connected to the basic principles.
Download or read book The Analysis of Small Glass Fragments Using Inductively Coupled Plasma Mass Spectrometry written by T. Parouchais and published by . This book was released on 1996 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inductively coupled plasma mass spectrometry using solution nebulization has the ability to analyze up to 70 elements with good precision, accuracy, and sensitivity and is, therefore, well suited for the trace element analysis of glass. However, the technique places severe restrictions on sample preparation. High concentrations of acids or dissolved solids, changes in sample viscosity and molecular compound formation can cause physical, spectral and chemical interference. Solubilization of the glass samples based on a three acid digestion procedure (HF, HNO3, HCl 2:1:1) has been found to minimize these problems. Up to 62 elements have been determined in a range of glass samples. Glasses that could not be distinguished on the basis of refractive index measurement could be discriminated. A procedure of measuring a range of elemental ratios, which eliminated the need for weighing, was used to compare small samples typical of casework.
Download or read book Elemental Analysis of Glass Fragments by ICP MS as Evidence of Association written by S. Montero and published by . This book was released on 2006 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inductively coupled plasma mass spectrometry (ICP-MS) was used to analyze glass evidence from a case in which a person broke a window in each of 15 vehicles in a parking lot in order to gain entry into the vehicles. The results of the analysis by traditional methods, which measure the properties of color, thickness, density, and refractive index, are also reported. A total of 15 known samples representing the windows on the cars and 42 questioned glass fragments recovered from the suspect and the police vehicle where the suspect was sitting were submitted for analysis. Density comparisons separated one of the known samples into three samples, increasing the number of known samples from 15 to 17. The concentrations of 16 elements were measured for all but three of the samples using an external calibration ICP-MS method with internal standardization. Color assessment (non-instrumental) separated the 17 known samples into two groups, and refractive index measurements resulted in six groups when the Emmons double variation method was used and ten groups when the Glass Refractive Index Measurement 2 (GRIM2) system was used. Elemental analysis, by itself, differentiated all of the known samples from each other and associated four of the known sample fragments with several of the questioned sample fragments. The informing power of RI, density, and elemental analysis comparisons is evaluated and a summary of the case results is reported.
