BlueClue Gunpowder Particle Tests are quick and dependable field tests for the detection of nitrates found in gunpowder.
These deposited particles may be collected using the included adhesive lifters. The lifter is then returned to the test, and the glass ampoule is broken. After several seconds of exposure to the liquid chemical, small blue specks will appear to indicate the presumptive presence of gunpowder particles.
