Cavity Leak-Out Spectroscopy Aids Ethane Detection
Ethane is an important chemical that is used in several industrial processes, such as the manufacturing of ethylene, but it also is an important biomarker for human health. Trace amounts of the odorless gas are created as a by-product of oxidative stress in the body, and they escape through exhalation of breath. The ability to confidently track ethane in one’s breath possibly could help identify people who have cardiopulmonary disease, atherosclerosis, cancer or Alzheimer’s disease.
