Summary
A rapid assay (response time of the order of minutes) using membrane inlet mass spectrometry was employed to assess the immediate effects of chemicals on methanogenesis. Changes in the levels of CH4, H2, O2 and H2S were continuously and simultaneously monitored directly in the liquid phase, in response to the presence of oxygen, sodium dodecylbenzenesulfonate, chlorhexidine diacetate, molybdate, sulphate, bromoethanesulfonate, formate, propionate or isobutyric acid.
