These include glass fragments, suspected accelerants from arson debris, gunshot residue on the hands of a shooter, blood stains, fibers, drugs, and even samples of hair. The cases…show more content…
In layman’s terms, mass spectrometry measures the masses within chemical atoms, molecules. Which, is also frequently used since it provides the strongest evidence in court. Most often, forensic chemists do not know the nature of the sample before they analyze it. In, “Joseph Bell Centre-About Joseph Bell,” by the Joseph Bell Centre-it states, “The results of their work are used in police investigations and court trials, at which they may be called upon to provide an expert testimony and explain their findings to a jury. The chemists rarely leave the lab, but there are a few that get to go out and do field work.” Out in the field they often observe the crime scene before the evidence is gathered, take pictures, and a major thing is figured out whether blood splatter patterns were normal, and if not what could have caused them to be irregular in the case of a homicide.
