The invention discloses a method for detecting an ion mobility spectrum of volatile anesthetic sevoflurane. Based on a reagent molecular assisted photoionization negative ion mobility spectrum technology, a real-time on-line sampling technology is combined, the ion mobility spectrum of the sevoflurane is obtained at different drift tube temperatures, the selectivity and sensitivity of the detection are improved, and the detection of the inhaled anesthetic sevoflurane is achieved.
Description
technical field [0001] Based on the reagent molecule-assisted photoionization negative ion mobility spectrum and real-time online sampling technology, the invention develops an ion mobility spectrum detection method for the inhaled anesthetic sevoflurane in the operating room environment. Background technique [0002] Sevoflurane (sevoflurane, chemical name is fluoromethyl-hexafluoro-isopropyl ether, C 4 h 3 f 7 O) is a new type of inhalational anesthetic, with anesthesia induction and fast awakening. It is an ideal inhalational anesthetic. Sevoflurane for inhalation is suitable for the induction and maintenance of general anesthesia in adults and children, and is suitable for both inpatients and outpatients , Excessive sevoflurane content in the operating room environment will have a certain impact on the human body, so continuous online monitoring of sevoflurane in the operating room environment is necessary. [0003] At present, photoacoustic infrared spectroscopy (PIS...
