John Calvin Giddings
Dr. J. C. Giddings studied at Brigham Young University and at the University of Utah where he received his Ph. D. He was fundamentally a physical chemist and was one of the pioneers in developing chromatography theory. In 1965 he published his classic work entitled the Dynamics of Chromatography and was coeditor of the chromatography series ‘Advances in Chromatography’. He developed another HETP equation which was unique in the use of a coupling term that allowed no dispersion (HETP=0) at zero mobile phase velocity. This was an exception to those HETP equations developed prior to his. Giddings also introduced a novel separating procedure involving a single phase called ‘Field Flow Fractionation’. He was the recipient of many chromatography awards for his contributions to separation techniques.
