Understanding Trace Materials Analysis Investigations

Friday, March 27, 2020 2:00pm - 3:00pm EDT  
Host: AIHA
By: Lawrence Wayne, Trace Materials Investigator , SGS Forensic Laboratories

Laboratories are frequently presented with client issues that are not readily solved by routine production analyses. These problems frequently relate to trace materials which are too small to be visually identified. With a moderate amount of specific analytical instrumentation, many of these problems are readily solved. This webinar will show how the use of a combination of optical microscopy, electron microscopy and vibrational spectroscopy can provide data which, when combined with critical thinking and problem-solving skills, can solve many unusual problems in both industrial and residential environments. These areas include, but are not limited to indoor air quality, contamination control, process control and general unknown materials analysis.

Learning objectives:
• Ascertaining the true the client problem
• Learning what instrumentation produces specific data types and how that data can be most effectively used
• Discovering how to most efficiently use specific analytical instrumentation to solve the problem at hand
• Understanding the use of critical thinking skills in trace materials analysis

Trace Materials Investigator, SGS Forensic Laboratories

Lawrence Wayne has been a trace materials investigator for 33 years. He received his bachelor’s degree in physics from Michigan Technological University then spent 8 years as a microscopist in the US Air Force. Mr. Wayne then joined SGS Forensic Laboratories (formerly Forensic Analytical Specialties, Inc.) as a microscopists and researcher. His experience includes development of new service lines for the company, including wildfire residue testing, respirable silica by FTIR and trace materials analysis investigations, which includes analysis on a wide variety of cases from unknown white powder analysis to criminal forensics investigations. Mr. Wayne is a court qualified expert witness in trace evidence examination and gunshot residue testing, spent three years on the board of directors of the American Society of Trace Evidence Examiners (ASTEE) and is a fellow of the Royal Microscopical Society. He is also an instructor in the graduate forensic sciences program at the University of California at Davis, where he teaches courses in forensic microscopy.
