Acetone in exhaled breath is a potential biomarker of diabetes mellitus (DM) and elevated breath acetone concentrations have been observed in DM patients. One of the near real-time and online breath acetone analysis techniques is cavity ringdown spectroscopy (CRDS) that has been demonstrated for breath acetone measurements in human subjects including diabetic patients in a clinic. In this work, we have constructed a ringdown breath acetone analyzer for the purpose of instrument validation.
