INSTRUMENTAL ANALYSIS of TRACE EVIDENCE WORKSHOPS WITH a FOCUS on INTERPRETATION INSTRUCTION: Free Online Courses

TRAINING MATERIALS DESCRIPTION:

These training materials are published as part of the dissemination strategies for NIJ grant (2010-DN-BX-K264, INSTRUMENTAL ANALYIS OF TRACE EVIDENCE WORKSHOPS) awarded to Florida International University. This work is designed as an introductory-intermediate course to the forensic examination of trace evidence and is a version of the live hands-on training workshops offered at FIU in 2011 and 2012. The purpose of this web version is to disseminate the training material to forensic examiners.

Examination and Comparison of Glass Evidence:

This course will be suitable as an introduction to forensic examiners with none or little experience in glass analysis and also as a continuing education tool for intermediate-level examiners. Following the completion of this online materials, the participants will be familiar with theoretical and practical aspects of different techniques for the forensic analysis of glass such as refractive index (GRIM), XRF, LIBS, LA-ICP-MS, and ICP-MS.

Mass Spectrometry for Trace Evidence Workshop:

This course will be suitable as an introduction to forensic examiners with some experience in mass spectrometry and also as a continuing education tool for advance-level examiners. This workshop offers a basic description of the processes and techniques involved in creating, controlling and measuring elemental or molecular ionic species by mass spectrometry techniques and its application to forensic sample analyses. Topics covered in the course include: a) Theory of mass spectrometry, b) Methods of ionization, c) Instrument Design and Operation, d) Combined Chromatography and Mass Spectrometry, e) Quantitative aspects of mass spectrometry. Case studies are also presented to exemplify some of the applications of mass spectrometry to trace evidence and forensic science.

Forensic Examination and Comparison of Paint, Tapes, and Adhesives with a Focus on Interpretation of the Evidence:

This course will be suitable as an introduction to forensic examiners with some experience in polymer, paint, and adhesive analysis and also as a continuing education tool for intermediate-level examiners. This course will provide a thorough introduction to forensic examination of these materials including fundamentals on instrumental analysis (FTIR, XRD, XRF, SEM, ICP methods, Pyr-GCMS, microscopy), handling and sample preparation, manufacture and composition, end-use applications, terminology, ASTM and SWGMAT standard methods of analysis, interpretation and evidential significance, validation studies on discrimination power, databases and sample collections, report writing, interpretation and expert opinion.

Elemental Analysis of Forensic Evidence with Focus on Interpretation of the Evidence:

This course review the basic principles and practical aspects of the application of different techniques for forensic elemental analysis of trace evidence, including XRF, SEM-EDS, ICP-MS, LA-ICP-MS and LIBS. A critical evaluation of the limitations and capabilities of these techniques, including sampling procedures, sample preparation methods, quality control, data analysis and interpretation of results is included. Lectures will include a review of the fundamentals of the above techniques and their application to the analysis of different trace evidence such as glass, paint, soil and biological matrices. The course will be focused on forensic aspects of statistical data, treatment match criteria, and interpretation of elemental analysis.
