A review of measurement methods of biological hydrogen

摘要: Abstract The current review purpose is to present a general overview of measurement methods hydrogen in dark fermentative production. gas performed with manometric and volumetric devices by manual automatic methods. measuring must be simple construct use, inexpensive, accurate, durable, economical. water displacement, plunger commercial meter, respirometer, were used measure volume rate biogas. For fraction the biogas, chromatography sensor employed. advantages drawbacks each method are highlighted some works their uses fermentation presented. Literature shows that displacement meter extensively biogas flow thermal conductivity detector Molecular Sieve 5A column nitrogen as carrier was widely employed biohydrogen.
