CH4 / CO2 detection for breath analysis in medical applications
Axetris, Laser Gas Detection, Leister Corporate, Breath Analysis
Axetris Laser Gas Detection modules can detect methane and carbon dioxide at the same time with one device only. This is used in medical applications, such as breath analysis.
Breath tests are an effective tool to investigate functional bloating, diarrhea, constipation, and suspected malabsorption, such as lactose and fructose. They form an alternative to more invasive procedures. Approximately half the biomarkers identified in human breath air can be detected by laser spectroscopic techniques. TDLAS is a robust and reliable technology to sense many of these biomarkers such as methane and carbon dioxide. The spectroscopic analysis of breath air can potentially shorten the period needed to conduct tests from hours to seconds. This would reduce mortality, prevent unnecessary hospitalization, and greatly reduce medical expenses. Because effective antibiotic therapy can immediately begin where appropriate, the risk of antibiotic resistance is also reduced.
Elevated methane levels can suggest indigestion and are a possible indicator of fructosemia or lactose intolerance. Axetris Laser Gas Detection technology is capable of measuring methane with unprecedented precision at trace levels. Methane provides important insights into the performance of the carbohydrate metabolism.
Carbon dioxide is a quality indicator, signaling whether the subject is taking sufficiently long and deep breaths. Low levels of carbon dioxide suggest shortness of breath. It has also been identified as an indicator of certain infections as well as liver malfunction and excessive bacteria growth. It is also often used as a reference to determine the amount of exhaled air that has been detected by the sensor to help determine the percentage concentrations of constituents.
