The BMP (biomethane potential) test system „Yieldmaster“ is a sophisticated and modular analysis system. In its basic setup it consists of a gas bottle connected via tubing to our precision gas volume measurement device, named BlueVCount. It measures up to 80ml/min with a resolution of 1ml and consists of a volume measurement cell as well as temperature and pressure sensor. The volume measured of every single device is given as norm volume (273,15K 1,013 bar). Additionally humidity can be compensated when necessary. For more advanced research tasks at universities or other research institutes the basic setup can be extended to also measure the gas concentration. Here we offer the well-known BCP gas analyzers for determination of CH4, CO2, H2, or O2. Direct installation at the fermentation vessel enables highly precise results and headspace corrections according to VDI 4630. Furthermore kintec investigations of different substrate are feasible. Additional equipment like water bath, stirring, different glass reactors (250-5000ml), pH electrodes and pumps may be connected and controlled applying our cost effective open bioprocess software BlueVis.

 

For measuring gas formation potential

To ensure effective biogas production determining the biological methane potential (BMP) of the input material is necessary.  Yieldmaster simplifies BMP comparison of different substrates and helps optimizing biogas yields. Using Yieldmaster you don´t have to consider minimal gas productions. After starting the experiment data for gas volume being produced and/or CH4 concentrations are logged automatically with BlueVis software. During fermentation in lab scale Yieldmaster can measure directly in the fermentation vessel. Like this there will be no loss of data, headspace as well as errors caused by gas leakage will be minimized. Treatment or filtering the gas is not necessary. Combining methane sensors and gas volume measurement results in continuous parallel biogas measurement. Gas volume produced as well as methane (biogas) concentration values measured are available online at any time.

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.
