Fermentation of organic materials – characterization of the substrate, sampling, collection of material data, fermentation tests

German VDI 4630 (2016) standard provides rules and specifications for tests to determine the biogas output of organic materials and residue gas production after anaerobic digestion which serve the interpretation and optimisation of biogas plants. Thus, it gives comprehensive and practice relevant support for the determination of the biogas orientation of organic materials.

AMPTS® series are well-recognised worldwide and recommended as the only automated test apparatus in VDI 4630 for biochemical methane potential (BMP), specific methanogenic activity (SMA) and residual gas potential (RGP).

– the instrument recommended by VDI 4630 test standard for BMP assays

Automatic Methane Potential Test System (AMPTS®) II is the research-standard analytical tool preferred by scientists and engineers for conducting various anaerobic batch fermentation tests. It consists of 15 parallel reactors and the same number of gas flow meters (flow cells) attached to a detection unit for online, automatic data acquisition.  This allows for the real-time investigation of a high number of feedstock samples with high precision and accuracy. The unique design makes the AMPTS II an extremely precise and accurate instrument in a wide range of applications.

– simplify the selection & pricing of substrates

AMPTS® II Light is the sister product of the AMPTS® II. It is the instrument of choice for process engineers and plant operators when selecting and pricing substrates in biogas plants. The instrument is used for analysing, with up to six test vials, biochemical methane potential (BMP), residual gas potential (RGP) as well as anaerobic biodegradability and specific methanogenic activity (SMA) assays. All of this is performed with easy access to sampling, analysis, recording and report generation fully integrated and automated.
