APPARATUS AND METHOD FOR ANALYSIS OF A FLUID SAMPLE

AN APPARATUS (100, 200) FOR ANALYZING A FLUID COMPRISES A CHAMBER (115, 215) TO RECEIVE A FLUID SAMPLE (114, 214). A PUMP (122, 222) REDUCES A PRESSURE IN THE CHAMBER (115, 215) BELOW A VAPOR PRESSURE OF A COMPONENT OF THE FLUID SAMPLE (114, 214). AT LEAST ONE LIGHT SYSTEM (101) PROVIDES A LIGHT AT...

Zusammenfassung:	AN APPARATUS (100, 200) FOR ANALYZING A FLUID COMPRISES A CHAMBER (115, 215) TO RECEIVE A FLUID SAMPLE (114, 214). A PUMP (122, 222) REDUCES A PRESSURE IN THE CHAMBER (115, 215) BELOW A VAPOR PRESSURE OF A COMPONENT OF THE FLUID SAMPLE (114, 214). AT LEAST ONE LIGHT SYSTEM (101) PROVIDES A LIGHT AT A PREDETERMINED MODULATION FREQUENCY TO THE FLUID SAMPLE (114, 214). AN ACOUSTIC SENSOR (117, 217) DETECTS AN ACOUSTIC SIGNAL CAUSED BY THE INTERACTION OF THE LIGHT AND THE FLUID SAMPLE (114, 214). A CONTROLLER (132, 232) RELATES THE ACOUSTIC SIGNAL TO AT LEAST ONE CHEMICAL COMPONENT OF THE FLUID SAMPLE (114, 214).
