Graseby Dynamics, maker of systems for detecting potentially lethal chemical and biological warfare agents.

Formerly Cambridge Electronic Industries

1970s Graseby's predecessors began supplying the UK Ministry Of Defence with products for anti-terrorist work, to detect explosive vapours; developed the Ion Mobility Spectrometry (IMS) technology and became a global leader in vapour detection based on this.

1980s The IMS expertise was extended to detecting chemical warfare agents.

Late 1990s: Graseby won the contract for the Prototype Biological Detection System (PBDS) for the UK Ministry of Defence - the forerunner of modern bio-detection and identification systems.

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