Abstract
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.
