Methane, carbon dioxide and ethylene sensing in development

We are developing optical sensing for methane, carbon dioxide and ethylene using fibre Bragg grating technology. The platform is in field testing, with the summary for each gas below distinguishing current work from target and exploratory applications.

Methane · CH4

On-farm livestock field trials

On a working farm with cattle and sheep, our methane readings are compared with an existing methane sensor in real conditions.

Tell us where you need to measure methane and what an evaluation or integration project would need to show. Humidity is a key condition for methane measurement.

Carbon dioxide · CO2

On-farm livestock field trials

Carbon dioxide is measured in our on-farm trials and has so far been checked against an existing sensor in the laboratory, with a field comparison to follow. Each gas requires its own performance assessment, so tell us how the carbon dioxide measurement fits within your application.

Ethylene · C2H4

Controlled atmosphere fruit storage target; further horticultural work exploratory

We are developing an ethylene sensor for controlled atmosphere fruit storage, targeting measurements in the tens of parts per billion (ppb). We are also exploring further horticultural applications such as monitoring in orchards. Selectivity is a key focus where other volatile organic compounds may complicate the measurement.

Measuring multiple gases

Demonstrated with methane and carbon dioxide

Many applications need more than one gas measured. Instead of adding a separate sensor for each gas, our platform selects absorption lines from each gas within one sensing system, at minimal extra cost. We have already used it to measure methane and carbon dioxide at the same time.

Got a particular gas combination that interests you? Each combination can be assessed for calibration, interference and performance. Reach out and we can chat about what’s possible.

Discuss the information your application needs

We love to chat about all things gas measurement. If you’ve got an application you’d like to explore, reach out!

Depending on your application, the discussion may cover:

  • The target gas or gas combination and useful concentration range.
  • Detection performance, measurement time and response requirements.
  • Humidity, interfering gases and other operating conditions.
  • Sampling, calibration and comparison methods.
  • How sensing would fit within your equipment or workflow.

Include what you already know. A complete specification is not required for an initial enquiry.
