Keith Clemenger was performing polarizability measurement Winston Saunders was optimizing the quadrupole mass analyzer for larger sizes and de Heer was measuring magnetic properties of small alkali clusters.
Also introduced by Thermo at ASMS was the Exactive benchtop LC/ MS system, which is based around the Orbitrap mass analyzer, in contrast to Thermo's LTQ-Orbitrap and LTQ-FT, the Exactive is not a tandem system, which greatly lowers its price, but it can still provide MS/MS.
