摘要： Systems, apparatus and methods determine the presence of a volatile substance in expired breath. Alcohol concentrations can be determined from expired breath through the use of electromagnetic detection. The systems, apparatus and methods allow measurements of volatile substances to be done accurately and quickly over a wide range of temperatures, and are easily incorporated into vehicles. An breath test system according to the invention comprises an air inlet (102) configured to receive an air flow for a breath sample; a detection cavity connected to the air inlet in which the air flow circulates, and comprising a first electromagnetic detection path configured to generate a first signal based on the presence of a reference gas in the air flow and a second electromagnetic detection path configured to generate a second signal based on the presence of a volatile substance in the air flow; and a logic in signal communication with the first detection path and the second detection path configured to determine a concentration of the volatile substance in the air flow based on the first signal and the second signal. The first and second electromagnetic detection paths may comprise thermally isolated emitters (108, 116) and detectors (106, 114), wherein the detectors (106,114) are selective of infrared absorption frequencies. The system may operate at temperatures greater than the ambient temperature and greater than the dew point.
