The use of the forensic examination and dating of inks on questioned documents has become common, and law enforcement agencies rely heavily on these techniques during criminal investigations whenever there is some question as to when a document was written. In this book, the authors describe the many advances that have occurred in the field of forensic examination and dating of inks on documents. Actual laboratory procedures for examining and dating inks and other related substances are described, as well as the forensic applications of these techniques in criminal and civil litigations. In addition, the authors provide discussion theories for each type of chemical analysis which serve as useful guidelines for explaining the science to lay juries. Major chapter topics include: Historical Development, Ink Analysis Training and Coordination, Ink Chemistry, Methods of Analysis, Forensic Comparison and Identification by Chromatography and Densitome-try, Instrumental Analysis of Inks, Ink Libraries, Ink Dating, Experiments on Ink Dryness Tests, Results of Case Examinations, and Court Admissibility of Relative Age Comparison Techniques. This book will be useful to chemists involved in dating examination work, lawyers trying cases using these techniques, and professors teaching in the field of forensic sciences. In addition, it will be useful serving as a methods manual and reference text for forensic science students.
