Biogas analysis

With the aim of appreciating the performances of our bioreactors the quantification of the contents of CH₄, CO₂, N₂, H₂, H₂S is carried out on our biogas . This measurement is taken by gas chromatography which makes it possible to separate the gas compounds which migrate at different speed on a column. Detection is done on a catharometer (principle of the Wheatstone bridge) whose intensity is fixed at 80mA.
