RESPIRATORY GAS MOISTURE SEPARATOR SYSTEM FOR MASS SPECTROMETER MONITORING SYSTEMS

摘要

RESPIRATORY GAS MOISTURE SEPARATOR SYSTEM FOR MASS SPECTROMETER MONITORING SYSTEMS Wet or saturated respiratory gas samples being monitored from one or more hospital patients are sufficiently dried for analysis by a medical mass spectrometer by a novel momentum separator in which the major part of the wet sample flows directly to an exhaust pump while a small sample for analysis is taken from the reverse angle tee connection in the momentum separator. This small sample containing water vapor, but without the heavier moisture droplets,is then heated to about 100.degree.C to maintain the water in the vapor state prior to entering the spectrometer inlet leak.
