Accurate quantitative measurement of biogas before and after treatment is a critical challenge in biogas production research, as precise estimation of the produced biogas not only allows for the evaluation of the efficiency of the biogas process but also facilitates the optimization of production conditions to achieve maximum yield. The displacement method (via water) is still commonly used due to its simplicity and lower cost, but it has limitations in terms of accuracy, especially when dealing with small amounts of biogas or specific system conditions. This method can be prone to errors due to variations in temperature, pressure, and volumetric changes, which can affect the precision of the results.

Alternative methods, such as the use of gas analyzers that directly measure the concentrations of methane, carbon dioxide, and other gases in the biogas, can provide more accurate, faster, and continuous results. Gas analyzers that use infrared spectroscopy or electrochemical sensors allow for precise, real-time monitoring of the biogas composition, which is essential for optimizing the production process and identifying potential issues. Additionally, the use of gas chromatography can provide a detailed analysis of the biogas components and ensure high precision in quantification. These advanced technologies enable a deeper understanding of the dynamics of biogas production, which can be highly beneficial in developing more efficient technologies and methods for recycling agricultural waste into biogas. Continuous and accurate measurement can contribute to improving the energy efficiency and ecological sustainability of biogas systems.

Dear Pius,

check out these portable MilliGas counters (and other gas meters) from RITTER:

They are rather cheap, battery-powered and very reliable for their size.

Best
