AMPTS stands for Automated Methane Potential Test System. This experimental unit makes possible the automated acquisition and evaluation of gas volume flows which arise from the anaerobic breakdown of very varying substrates. In this way, with modest laboratory effort it is possible to measure gas production and breakdown rate, and from this to estimate and calculate important operating characteristics such as well time, type of substrate used, mixture ratio of the substrates used, and substrate preparation.
AMPTS II is based on the principles of conventional systems for determining gas potential. The lab fermenter and CO2 fixation components are supplemented by on-line volume flow measurement, and automated data acquisition and evaluation.

AMPTS II is based on the principles of conventional systems for determining gas potential, and so its results are comparable with all traditional methods. This device conforms with directive VDI 4630 on the fermentation of organic materials. The lab fermenter and CO2 fixation components are supplemented by on-line volume flow measurement, and automated data acquisition and evaluation. This procedure replaces the classical batch trials efficiently, and in a way that saves resources. Once it has been started, the experiment runs for the whole of the fermentation period, without the need for human intervention. The current data is available on-line at any time.

The fermentation process in a biogas plant is very complex. The quality of the biogas depends on the substrate, and is therefore an important cornerstone for the efficiency of a biogas plant. A substrate analysis makes it possible to investigate problems in the process chain in good time, and to ensure a problem-free fermentation process.
With the aid of the AMPTS II, a substrate analysis is simple and user-friendly to conduct. Biogas plant operators can therefore determine the true methane potential of their input materials, and can compare different pretreatment alternatives. Even agricultural wastes, foodstuff wastes, industrial waste water, and sewage sludges can be investigated for their biogas potentials.
The production of bio-methane is measured continually, and the values are standardised by means of permanent temperature and pressure correction.
Even sample weighing is very simple to execute. A sample weight field is integrated into the software, and so human error is precluded.
