The power of chemistry combined with data analysis. At your fingertips.

Pioneers in GC-IMS technology

Delivering fast, accurate, lab-quality analysis on-line, at-site, in the laboratory and at point-of-care.





ImspexGroup brings together diverse skill sets with a common interest in the power of science for health and economic prosperity. Accomplished international experts combine deep analytical chemistry knowledge, data analysis skill, medical technology expertise and sound business acumen to create innovative solutions for patients and customers.


ImspexGroup provides cutting-edge analytics solutions where early warning signals are needed. Our versatile combination of gas chromatography (GC) and ion mobility spectrometry (IMS) has already proven itself in medical detection and medical diagnosis scenarios and in industrial sectors as diverse as food and beverage processing through to refining wastewater treatment.


Imspex Diagnostics and its technology development partner have honed their collective high-end chemistry analytics expertise across a wide range of industrial applications. When gaseous particles come into play, Imspex Diagnostics can measure and characterise these using our proprietary GC-IMS technology.

G.A.S. founded in 1997 is an instrument manufacturing high-tech company delivering tailor-made solutions to those in the food quality control, environmental, and human breath analysis. Comprising of an interdisciplinary team, G.A.S. measures traces of volatile organic compounds (VOC) in air, human breath and the headspace of liquid and solids.


Imspex Medical brings the combined power of GC and IMS analytical techniques to bear on earlier detection and diagnosis of disease and quicker, more targeted management of health status. Together, GC-IMS techniques generate insights that open a window onto a body’s physiology, metabolism and state of health.

Imspex Diagnostics was born in 2011 when Imspex Diagnostics Ltd was founded in a South Wales valley following a death in the Imspex family.

It was an avoidable death. This death would not have happened with an earlier diagnosis.

Ours is not a unique story and thankfully this was not where the story ended for us. What is unique is the business that grew out of the experience – a dynamic, determined and entrepreneurial mix of analytical chemistry experts, data science specialists, medical device and healthcare veterans and sound business acumen with a shared goal of developing and distributing an early warning system that saves life, time and money in medical, environmental and industrial matters.

Since then the business has grown, acquired international partners, G.A.S. mbH, a high-tech analytics developer and manufacturer of GC-IMS instruments and solutions, secured international interest in its shareholding and set up Imspex Medical as a dedicated analytical division for medical and healthcare screening and diagnosis.

The Imspex story will continue as our business grows, embraces opportunities and navigates bends in the road. Wherever the road may lead, we remain people with a passion for putting great science to use for the greater good.


Our proprietary technology combines gas chromatography with ion mobility spectrometry to form a robust, selective and ultra-sensitive GC-IMS combination that has multiple research, industrial, environmental and, most recently, medical applications. The technology was developed and is manufactured by G.A.S. mbH who was acquired by Imspex Diagnostics Ltd in 2013. Imspex Diagnostics is also G.A.S. mbH’s representative for UK equipment sales.
