[14] Giddings also envisioned the capabilities of Supercritical fluid chromatography,[15] by developing the theory and ground work of dense gas chromatographic system.
[16] Eventually Prof Giddings invented the one-phase separation technique called "field-flow fractionation" (FFF).
The FFF system extends the range of chromatography upward to include macromolecules and particles of almost every type and size, from 0.001 to 10 μm and beyond.
[2] Giddings received numerous honors for his work[2] including American Chemical Society Awards in Chromatography and Electrophoresis, in Analytical Chemistry, and in Separation Science and Technology.
On May 27, 1987, Giddings received an honorary doctorate from the faculty of pharmacy at Uppsala University, Sweden[20] Besides being an exceptional scientist, he was also a passionate outdoor sportive practicing climbing and kayaking[21][2] in Utah and a fervent defender of the environment.
