Extractive or in-situ gas analysers: which is best?

There are two main options for gas analysis in industrial processes or emissions; the analyser can be located inside the gas stream (in-situ), or...

Sponsored Content: “Laser-focused on net zero”

Mark Naples, General Manager at Umicore Coating Services writes: Laser absorption spectroscopy is a powerful tool for detecting trace gases and has been widely used in the monitoring of atmospheric greenhouse gases, pollution, and respiration processes, including human breath analysis. The detection is based on the absorption of light when it propagates through a medium.

OBW Technologies is a leading national provider of portable and fixed gas detection instruments and solutions, based in Ireland. Over the last 10 years, says the firm, they have brought together a team with the best minds in gas detection using the best technology to advise their clients on all aspects of their fixed and portable gas detection requirements.

Burping bacteria

As greenhouse gases (GHGs) bubble up across the Arctic, researchers are trying to identify other trace gases from soil microbes that could shed light on what is occurring in the melting permafrost.

Connected detector

A new single-gas detection wearable from Blackline Safety is said to offer fast incident response time and a more efficient way to manage safety and compliance.

Detecting leaks before they occur

A group in the US claims to have made an important advance with the transducers that use ultrasonic guided-wave technology to detect anomalies in pipes, helping users prevent leaks before they start.

CO2 imaging

Researchers in Madrid have used a novel near-infrared-light imaging technique to capture the first cross-sectional images of carbon dioxide in the exhaust plume of a commercial jet engine. The new technology could help accelerate turbine combustion research aimed at developing engines and aviation fuels that are more environmentally friendly.
