This document discusses various forensic science techniques used to analyze evidence, including chromatography, audiometry, ballistics, toxicology, microscopy, photography, anthropology, and biology. Chromatography separates colored chemicals using differences in molecule size and solubility. Audiometry detects and analyzes sounds at crime scenes. Ballistics examines the flight, behavior, and effects of projectiles from guns and rockets. Toxicology analyzes the effects and treatment of poisons. Microscopy, mass spectrometry, and other techniques are used to measure and examine samples. Anthropology and biology can provide information about individuals from examining bones and biological evidence like DNA.
