Graseby Dynamics

Graseby Dynamics established a world leading position in products that detect potentially lethal chemical and biological warfare agents. It was at Graseby that scientists developed the Ion Mobility Spectrometry (IMS) technology that lies at the heart of many Smiths Detection trace detection systems. 

In the 1970s Graseby began supplying the UK Ministry Of Defence with products  for anti terrorist work, to detect explosive vapours and it became a world leader in vapour detection, based on IMS. That expertise was extended in the 1980s to chemical warfare agents for the MoD. 

A major advance into biological detection came in the late 1990s when Graseby won the prototype biological detection system (PBDS) for the UK MoD, as the forerunner of today’s bio detection and identification systems.

Graseby plc was acquired by Smiths in 1997 and Graseby Dynamics became the company's first venture into the detection sector.
