Ceramic radiation source assembly with metalized seal for gas spectrometer

摘要: A radiation source assembly is provided that particularly apt for use in an anesthetic gas monitoring device (e.g., a spectrometer) to enhance maintenance of initial calibration conditions therewithin. In one embodiment respiratory spectrometer includes containment defines internal area(s) within which ceramic source, optical assembly, sample and detection are positioned. The positioning supporting the relative area monitor. provides enhanced sealing between adjoining componentry. selectively retractable from permit periodic servicing replacement source) without requiring disassembly spectrometer.
