Forensic Microanalysis Law and Legal Definition

Forensic microanalysis refers to analyzing, identifying, and comparing microtrace evidence upon instrumentation, which is contained in standards, operating procedures, test protocols, machine tolerances, owner manuals, and dictionaries.

The following is an example of a case law on forensic microanalysis:

The forensic micro analyst conducted the gunshot residue test, for which he took samples from defendant's hands and determined that the backs and palms of his hands had high levels of lead, barium and antimony. In forensic micro analyst’s opinion, the very high level of these elements indicated that defendant had either fired a weapon or handled a recently fired weapon before the test. It was also his opinion that according to the test results it was more likely that defendant had fired the weapon himself rather than having handled one after someone else had fired it. [People v. Baisten, 203 Ill. App. 3d 64, 69 (Ill. App. Ct. 1990)].
