BCP-CH4 analyzers are suitable for measuring methane in biogas applications or process development with methanogenic or methanotrophic organisms. BCP-CH4 gas sensors can be used in any scale of biogas process from lab to industrial scale digesters and all scales of industrial microbiology processes from lab to manufacturing scale. Data transfer to process control systems is simple. BCP-CH4 can be used directly on the gas stream with no requirements for pretreatments. All BCP-analyzers are available with aluminium (pilot to industrial scale use) or PA (lab scale) casings. BlueSens offers the Yieldmaster series for customers interested in BMP (bio methane potential) determinations.

BCP-CH4 – optimize your output

  • Direct integration in gas pipes, installation of additional gas pipes is not necessary
  • No extra gas cooler, no pumps
  • Fast installation due to standard connection
  • Low maintenance costs
  • Factory calibration using certificated test gases

Application areas

  • biogas production plants
  • chemical industry
  • digestion reactions
  • methanogenic or methanotrophic organisms

Don't waste budget and "Use what you have"

Before you go and buy something new: check your lab! It might be enough to just buy several new components. We can show you how to turn your older equipment into a modern, fully equipped and controlled system.

Go and check your lab cabinets for 

  • an (older) culture vessel, bioreactor or fermenter
  • pH, pO2 probes
  • agitator control
  • digital mass flow controller or flow meter
  • pumps for feed addition and pH control
  • open software BlueVis 4.0
  • off-gas analyzers suitable for your application

Do you already have some of these items? — Perfect! With open bioprocess software BlueVIS we will connect all components and make your system run. Various communication protocols already have been integrated in BlueVIS. If yours is not supported yet, we will realize it.

Use what you have — Think sustainable and keep your invest low

  • Don't waste money on installation fees or trainings
  • Use equipment from manufacturers that you want to and not that you're told to
  • BlueVIS 4.0 is compatible with other process-control software via OPC

Benefit from continuous off-gas data

See what´s happening when it´s happening. MS and off-gass analyzers - it doesn´t have to be either or but can also be complementary. Read here why and how to benefit from continuous off gas measurement made by BlueSens although you already might have a mass spec.
