Biogas BMP analyzer Yieldmaster: simultaneous methane (CH4) and volume determination

The Yieldmaster

The biogas analyzer Yieldmaster (BCS-CH4 biogas) is a highly developed measuring system consisting of microprocessor controlled infrared-gas sensors, precision volumenometers (MilliGascounter®*) and the related BACVis data acquisition software.

For measuring gas formation potential

To ensure that the biogas production is very effective it is necessary to know the biological methane potential (BMP) of the input material. The Yieldmaster will make it easy for you to see find out the BMP of different substrates and to guarantee the maximum yield for your biogas process.

When using the biomethane potential analyzer Yieldmaster you do not have to consider minimum gas volumes produced during the running experiment. As the experiment is started, the CH4 concentrations and the gas volumes are recorded automatically. With the integrated temperature measurement the software BACVis immediately converts the measured gas into the standard volume.  Using methane sensors directly in the fermentation container means, none of the measurement data is lost and errors caused by gas leakage or other malfunctions are minimized. The combination of the methane sensors and the precision volumenometers results in a parallel gas metric flow measurement so that both the generated gas volume as well as the biomethane content are available online and are continuously and automatically documented by BACVis. The new compensating reservoir device guarantees continues measurement under all circumstances.

New flow adapter and inexpensive fermentation vessels

Inexpensive measurement of biogas in the laboratory

Especially for use in the Yieldmaster systems there is a special flow adapter for use along with inexpensive preserving jars to choose from now. The flow adapter can be easily connected to round jars with a volume of up to five liters and provides two connectors for BCP-sensors. In most cases the set-up consists of a CH4 and a CO2 sensor, but for other types of experiments there are other possible installations (for example, CH4 / O2 or CH4 / H2). In addition, the flow adapter has a standardized PG13.5 port through which, for example, an additional probe can be installed. The experiments for the production of Biomethane often last for several days. Often it is recommended to run a larger number of experiments at the same time run enough variations and comparison tests in a manageable timeframe. The use of inexpensive jars in this case represents an attractive alternative to traditional fermentation vessels and small fermenters.
