SPN: A halothane gas analyzer is a device intended to measure the concentration of halothane anesthetic in a gas mixture. The device may use techniques such as mass spectrometry or absorption of infrared or ultraviolet radiation.,UMD: Environmental/gas system analyzers designed to measure and display the concentration of halogenated compounds used for anesthesia; some analyzers can also measure nitrous oxide concentration. These analyzers are typically portable units based either on an optical interference photometer (i.e., interferometer) or on an infrared spectrophotometer. Halogenated anesthetic analyzers are mostly used to check anesthesia unit vaporizer accuracy usually at the gas outlet during inspection procedures; they are also used to check leaks in anesthesia systems, or in the environment, especially at sites where accumulated gases would affect personnel (e.g., anesthesiologists).
