Studies have demonstrated the interaction of hydrogen and methane in carbohydrate malabsorption, small intestinal bacterial overgrowth and other digestive disturbances in some patients. The BreathTracker™ SC is the result of advancements to the MicroLyzer™ SC which was the original gas chromatograph developed to measure both H2 and CH4 in a single sample of alveolar air by the most simple, reliable and accurate method. The added feature of the BreathTracker™ SC is its ability to calculate the alveolar concentrations of components in breath samples which may have been imperfectly collected or accidently contaminated by mishandling or transport. The instrument generates a correction factor based on the degree of dilution of alveolar CO2 with dead space air or with inspired air during an improper collection procedure and applies it to the trace gas measurements. Within 50 seconds after introducing the sample, the BreathTracker™ SC will displays sample H2 (Hydrogen), CH4 (Methane), and CO2 (Carbon Dioxide) concentrations on the alphanumeric backlit data display. Then, with the push of a button the instrument activates the correction feature and displays the correction factor (Alveolar CO2/Sample CO2) and the corrected values for H2 and CH4. The BreathTracker™ SC separates the components by the basic principle of gas chromatography, using room air as the carrier gas, which is pumped through the system by an internal circulating pump. Hydrogen and Methance are separated from all other reducing gases and from each other, and are carried past a solid-state sensor, which you won't find in the electrochemical (fuel sensor) portable devices in the field today. The sensors are affected only by reducing gases, so it is unaffected by other gases in the sample. There are other BreathTracker models available, please download the "BreathTracker Series Infomation" sheet to determine which model is most suited for your needs. |
