Abstract

The invention discloses a small portable mass spectrum on-site rapid detection method for fentanyl substances. The method comprises the following steps: (1) selecting a point template; (2) loading a sample: dropwise adding the sample and an acetonitrile solution of 3-nitrobenzonitrile on the sample application plate to form a crystal mixture; and (3) carrying out analysis and detection: setting parameters of the small portable mass spectrometer, tightly attaching the crystal mixture on the sample application plate to a sample inlet of the small portable mass spectrometer, and ionizing the sample to complete detection and analysis of fentanyl substances in the sample. The small portable mass spectrum detection method for fentanyl substances is established, does not need an extraction solvent, voltage, laser or gas, is simple and rapid, and is suitable for on-site rapid detection of fentanyl substances.

Description

technical field [0001] The invention relates to a detection method of chemical substances, in particular to a small-scale portable mass spectrometry field rapid detection method for fentanyl substances. Background technique [0002] Fentanyl (Fentanly) is an opioid receptor agonist synthesized by Belgian scientist Paul Janssen in 1960, and its chemical name is N-[1-(2-phenylethyl)-4-piperidinyl]-N- Phenylpropanamide, the analgesic effect is 80 times that of morphine, and it is often used clinically for intraoperative and postoperative anesthesia. Fentanyl analogues are formed by modifying three parts: phenylalkyl group, piperidinyl ring, and propylalkylamide. The types include remifentanil, carfentanil, sufentanil, etc. The analgesic effect is stronger than fentanyl. For example, the analgesic effect of carfentanil is 100 times that of fentanyl and 10,000 times that of morphine. [0003] Fentanyl has a powerful analgesic effect, a short onset time, and is very easy to obta...
