3. What is a distance determination? How is this done? The process of estimating the distance between where a shot is fired and its target. It is done by looking at the patterns of powder residue and the shot pattern. 4. What is the Greiss Test? A test that uses chemicals to help develop gun powder residue patterns. 5.

Vacuum distillation apparatus was set up and residue placed in a round bottomed flask. Residue was distilled under reduced pressure by way of vacuum for approximately one hour. Residual toluene was collected in one vial between 24–28 °C then a slight temperature drop was observed indicating all toluene had been removed
