Informationen zum Autor Robert D. Blackledge , now retired, was the senior forensic chemist at the Naval Criminal Investigative Service Regional Forensic Laboratory in San Diego, California. He has a bachelor's degree in chemistry from the Citadel and a master's degree in chemistry from the University of Georgia. He serves as an Adjunct Professor in the Master of Forensic Sciences Program at National University, San Diego, California. Klappentext This title brings forensic scientists and chemists up-to-date on the latest instrumental methods for analysing trace evidence, including mass spectrometry, image analysis, DIOS-MS, ELISA characterization, statistical validation, and others. Illustrates comparative analysis of trace evidence by both old and new methods. Explains why some newer methods are superior to older, established methods. Includes chapters on analysis of DNA, ink, dyes, glitter, gun powder traces, condom trace evidence, footwear impressions, toolmark impressions, surveillance videos, glass particles, and dirt. Discusses applications such as mass spectrometry, image analysis, desorption-ionization on silicon mass spectrometry (DIOS-MS), ELISA characterization, and statistical validation.
