Celtic Recycling Case Study ‐ Custom Gas SF6 Analysis Using Nexis GC‐2030

SF6 is an inert gas with a global warming potential many thousands of times greater than carbon dioxide, making it extremely harmful to the environment.


Legislative changes in the EU and UK are set to make it more difficult to import virgin SF6 to mitigate its harmful effects. Celtic Recycling of Newport, Wales, has implemented the first SF6 recycling workflow in the UK to help meet the UK's demand for SF6. Jenny Rapp leads the laboratory at Celtic Recycling, and recently implemented a dual column, dual detector GC‐2030 to expand their GC capabilities from high-throughput PCB analysis to now include gas sampling for this green project.

Shimadzu's own Pete Klawitter provided expertise in engineering this bespoke gas analyser based on a GC-2030 with Shimadzu's patented BID detector.

Jenny's comments:

I am really pleased with the new system and enjoy working with it. It is easy to use, and I can generate customized reports that look very professional with just a few clicks. Maintenance is quite straightforward, and it is very easy to change columns; having a light inside the oven is a definite advantage – I hadn't realized how dark the oven is until now! The product specialists at Shimadzu have been great, providing training and helping me to set up the methods. It's good to know that I can rely on their support.
