'fast scanning' facilities so that mass spectra could be taken across the peak as it was eluted and have sufficient sensitivity to provide spectra from even peaks from trace materials. This was necessary to ensure the peak was homogeneous and not a concentration envelope containing two or more peaks. The design of the first mass spectrometer to be specifically constructed for a GC/MS system evolved largely from the work of Bill Kelley at the Unilever Research Laboratories at Sharnbrook and Ted Adlard at the Shell Research Laboratories at Thornton in the UK. Initially the work was carried out on a small mass spectrometer the MS2, but the ultimate result of their work was the design of the MS 12 which was a (what was then considered) 'fast scanning' mass spectrometer. The basic design of the MS 12 is shown in figure 2 (Banner et al. Ref 5).
