Identifying unknown substances in the field upon seizure is a critical step in the drug investigation process. It provides information that helps law enforcement make arrests, obtain search warrants, and even question suspects. Inexpensive chemical colorimetric wet test kits have been the field test of choice for decades. These colorimetric wet field tests require an officer to take a sample of the substance and place it into a small plastic pouch that includes a plastic vial inside. The officer then intentionally breaks the vial and waits for the chemical in the vial to react with the suspected drug to confirm its identification. The tests have evolved over the years, but the general process and chemistry have remained the same.
