Optical and Acoustic Gas Detection GASG Meeting

This much-awaited, first face-to-face Gas Analysis and Sensing Group event since the pandemic began, will be held on 16th June at the National Museum of the Royal Navy on Portsmouth's Historic Dockyard. This informative scientific meeting will also give delegates the chance to look round the Naval attractions after the meeting.

The title of the meeting is Optical & Acoustic Gas Detection - “Making Waves”.

This encompasses a wide variety of gas detection methods, from photoacoustics and optical methods through the near and mid IR to THz, including talks on NDIR which is widely used for monitoring CO_2 and other gases. These technologies uniquely offer the opportunity to change detection geometries with optical fibre based systems or remote detection. And you can't get more remote than to measure the atmosphere on an exoplanet. So, it promises to be another great meeting with something to interest everyone.

The event will also be our first hybrid meeting, so that if you can't attend in person, you will be able to join online. We hope to make this as interactive as usual. We hope that hybrid meetings will offer the best of both worlds. Note that if somebody from your organisation is attending in person, your free online quota still applies, so others from your organisation can also attend virtually. It's a great way to extend the skills of your colleagues and help them stay up to date with the latest technology. For more information, please contact us today.
