OVERVIEW OF INSTRUMENTAL ANALYSIS

Flashcards covering key terms and concepts from the lecture on forensic science methodology.

Classes and Types of Evidence

Categories of evidence used in forensic science, including physical, chemical, and biological evidence.

Physical Evidence

Objects or pieces of objects such as drugs, plastics, glass, and body fluids that can be used in forensic investigation.

Chemical Evidence

Identification of substances such as paints, pigments, explosives, and drugs through chemical analysis.

Biological Evidence

Includes bodily substances like blood, tissues, and genetic samples that can provide crucial information.

Mass Spectrometry (MS)

An analytical technique used to measure the mass-to-charge ratio of ions, useful for identifying substances.

Microscopy

A technique that uses microscopes for detailed examination of physical evidence, such as fibers and hairs.

Electrophoresis
