Mass Spectra: Theory and Interpretation

This three-day classroom course is designed for forensic scientists who use mass spectrometry in the analysis of physical evidence. It also is useful for supervisors who review mass spectral analytical data. Types of instrumentation and various techniques of mass spectra generation are presented. Basic interpretation of mass spectra is discussed, with emphasis on the types of chemical compounds commonly identified in forensic laboratories, particularly controlled substances and arson accelerants. Practical class exercises will apply fundamental principles used to interpret mass spectra. This course is open to criminalists, toxicologists, and supervisors who are responsible for generating and/or reviewing mass spectral data. Students should be familiar with the operation of mass spectrometers and the presentation of mass spectra.
