Electroseparation

David Simpson's thesis provides a guide to his work on electroseparation performed while he was a member of this group. There is also a poster that he presented at the 49th ASMS Conference on Mass Spectrometry and Allied Techniques, which is available here as either a pdf or a html file. David has also provided additional information on his research. You may also wish to look at an older paper we presented at the Desty Meeting for Innovation in Separation Science in October 1999.

One of the most important papers ever published on the subject of CEC was authored by John Knox and Iain Grant (Chromatographia, 1987, 24, 135). Iain Grant's PhD Thesis is now available on-line.
Animation of the Separation Process
The purpose of a separation is to resolve overlapping analyte bands in some way. The above animation represents bands moving along a column at different speeds, resulting in an efficient separation. The animation is presented as if you could look into the column and see the bands moving. The bands all remain the same size throughout the separation, although in a real system they would broaden to some degree. The first half of the animation shows coloured bands moving individually at different speeds while the second half shows the overall picture, more in line with what would be seen using an absorbance detector.
