Abstract
The use of biogas for several applications is directly related to its composition, especially the concentration of methane. To analyze biogas samples in small systems, it is proposed to develop a low-cost system, with a methodology based on a set of chambers, for diluting the biogas sample to the levels where a simple and low-cost semiconductive sensor can be used accurately. For interpretation of the signal extracted from the sensor, the methods provided in the manufacturers' manuals are evaluated, as well as methods developed particularly for this project. Results are cross-checked with external analyses to ensure system accuracy. Among the methods evaluated, those with the greatest potential for use in the system are those developed particularly for this application, and should be recalibrated and validated experimentally in the continuation of the project.
