Education
1955 B.S. Chemistry (Magna cum Laude), University of Arizona, Tucson, Arizona
1957 M.S. Analytical Chemistry, Purdue University, West Lafayette, Indiana
1959 Ph.D. Analytical Chemistry, Purdue University, West Lafayette, Indiana
1960 Fulbright Postdoctoral Fellow, Eindhoven Technical University, Eindhoven, The Netherlands
Research Interests
Microbore and Packed Capillary HPLC Columns. Microbore HPLC columns 1 mm,
1.D. x 50 mm as well as 530/um, packed fused silica columns are evaluated
in selected analytical and biological applications. Performance studies
focused on column efficiency, effect of flow rate, and minimum detectable
quantities obtained with a UV detector. Since very low flow rates can be
used (10 ml/min.), the sensitivity of a concentration-dependent type
detector can be increased. Effect of sample volumes, samples concentration,
and detector dead volumes are evaluated and conclusions made as to
applicability of these new columns. These columns show increased
sensitivity, decreased solvent consumption, and simplified interface
capabilities for LC/LC, LC/MS, and LC/FITR.
Fast GC. Using small i.d. columns (50 um), short lenghts (1 m) and fast
flow rates, most GC analyses can be done 5 to 10 times faster.
GC/MS. Trace and ultratrace analysis of organic chemicals in soil, water
and food products.
