This site focuses on the Selected Ion Flow Tube, a device invented by Professor David Smith in order to investigate ion-chemical processes in space and the atmosphere.
The first instruments to be built were bulky prototypes, filling a whole laboratory. As well as developing systems for his own use, David traveled the world, helping other scientists to build instruments for themselves. Many of these systems are still in use today, contributing further insights into fundamental ion chemistry.
In the early 1990's David was working in Innsbruck and was joined by Patrik Spanel, who brought the capability to apply automation and computer based methods to the team.
In the mid 1990's the team moved to the Center for Science and Technology in Medicine at Keele University in the UK. The emphasis changed from using SIFT for physical research, to developing its capability as a trace gas analyser for medical research. In collaboration with Europa Scientific Limited and then Instrument Science, second and third generation instruments were developed , specifically for this type of application.
Using these instruments, David and Patrik have undertaken numerous novel experiments and published extensively. These have stimulated interest from other scientists around the world.
Third generation SIFT-MS instruments are now commercially available and are being used for cutting-edge research in a wide range of disciplines.
