4 credits · Forensic Science · Penn State

Analytical and instrumental methods used in the forensic sciences with special emphasis on the analysis and characterization of trace evidence. Forensic chemistry is a classroom and laboratory based course designed to introduce the student to the forensic analysis of trace evidence according to established forensic procedures. The trace evidence can include paint, fire debris, glass, controlled drug substances, blood alcohol analysis, fibers, smokeless powders, inks/dyes, gunpowder, and low explosives. The focus of the course will be on identifying and understanding the nature of the samples, common sample preparation methods, chemical and analytical instrumental methods, and proper collection and storage of evidence. The course will simulate the methods in a standard forensic chemistry laboratory. The analytical methods will include microscopical, spectroscopic, trace elemental, and chromatographic analytical tools that are commonly used in these laboratories. The course will rely heavily on the students' knowledge and skills that have been learned or acquired during their studies in the pre-requisite course work. The pre-requisite knowledge include, but are not limited to: algebra, calculus, general chemistry, organic chemistry, analytical chemistry, basic statistics, polarizing light microscopy, spectroscopy theory, chromatography theory, proper evidence handling practice, and good writing skills. All of these knowledge areas are represented in the required pre-requisite courses which are CHEM 213 AND CHEM 227 AND ( FRNSC 411 OR CHEM 431W ).
