Detects therapeutic and illicitly synthesized forms of acetyl fentanyl and fentanyl. Useful in many situations: pain management, dependency/ rehabilitation, methadone clinics, and drug courts. Fentanyl is screened via enzyme immunoassay (EIA). Acetyl fentanyl and fentanyl are confirmed on GC-MS equipment.
To use this method, make a diluted bleach solution with one part bleach and one to two parts water. Fill your plastic container with the solution and let it soak for about half an hour. After itâs done soaking in the solution, give the container a good scrubbing with hot water and dish soap.
As an extra safety precaution, wrap a piece of clear packaging tape around the ends of the glass tube to protect against breakage. CAUTION: Do not substitute a piece of plastic tubing in place of the glass. The plastic tube will break due to the lower pressure produced in the tube by the reaction. DISPOSAL The alcohol solution produced in this experiment can be safely poured down a drain with running water. EXPERIMENTAL PROCEDURE Add some food color to approximately 50 mL of water.
