Chimera Max gas analyser beside three silver gas sampling bags

Chimera Max

Automated multi-gas analysis for up to 15 low-flow reactors

Chimera Max automatically measures CH₄ and CO₂ from up to 15 gas sources, switching between channels to provide frequent readings at flow rates as low as 40 mL/h. Connect it directly to BMP systems, continuous reactors or other gas-producing experiments to reduce manual sampling and track changes in gas quality over time.

  • Minimum 40 mL/h
  • CH₄, CO₂ and 2 more sensors included
  • Online connection to up to 15 channels

Chimera Max is designed for researchers and operators who need more than CH₄ and CO₂.

Automatically capture gas composition that manual sampling can miss

In the past, lab-scale biogas setups such as BMP have lagged behind industrial plants in gas composition readings. The challenge of only producing low flows has meant that all gas composition options always present a compromise: whether it’s infrequent data readings (gas bags), washing of important gases (H₂S, CO₂…) or complicated procedure (GC). The Chimera Max eliminates these issues by providing a convenient and easy to operate machine that measures gas composition online, semi-continuously and across up to 15 channels.

Already have BMP reactors, CSTRs or fermentation vessels?

Chimera Max can be connected to most laboratory gas-producing systems using standard tubing connections.

You don't need Anaero reactors.

Maximise reading frequency

Electrochemical sensors require ~500ml gas in a short time. Many BMP and other lab setups don't produce these volumes, so to fix this, we use our recirculation technology.

  1. Whilst 1 channel analyses, 14 collect gas in bags.

  2. When enough gas has accumulated in the bag for an electrochemical sensor reading (H₂, H₂S...), an internal pump automatically recirculates it back through the sensors.

  3. Gas analysis frequency is maximised, with no manual intervention.

Configure your Chimera Max

Start with CH₄ and CO₂, then choose two electrochemical sensors to measure the gases you need for your research or gas monitoring. Our modular gas sensors use NDIR and electrochemical technology.

Frequently asked questions

  • What is the Chimera Max used for?

    The Chimera Max is a multi-channel gas analyser for CH₄ and CO₂, that works for low gas flow systems such as BMP tests. You can connect your gas sources to the Chimera Max at the beginning of your tests, and automatically receive gas composition data.

  • What is the difference between the Chimera and the Chimera Max?

    The Chimera is fit with CH₄ and CO₂ sensors, with the capacity to add 2 more NDIR sensors. The Chimera Max is additionally compatible with electrochemical sensors, allowing for the reading of gases such as H₂S and H₂. Chimera Max is also fit with a recirculation pump, which allows it to draw back in collected gas from the outlets for analysis, once sufficient gas is collected. This is necessary because electrochemical sensors require larger volume for accurate reads.

  • Can I connect other brands' reactors to the Chimera Max?

    The Chimera Max can be connected to any reactor setup, given that there is a gas hose outlet with a continuous stream of gas.

  • Can the Chimera Max only be used for anaerobic digestion studies?

    The Chimera Max is a versatile machine which can be used for many applications, where there are multiple streams of gas that require composition analysis. Some alternative applications are: aerobic fermentation tests, biohydrogen, fuel.
