Dr. Pawliszyn’s Research Group (Analytical Chemistry)

The primary focus of Professor Pawliszyn's research program is the design of highly automated and integrated instrumentation for the isolation of analytes from complex matrices and the subsequent separation, identification and determination of these species. An important objective is the development and application of state-of-the-art, integrated and automated analytical methods and instrumentation, for on-site analysis and monitoring.

Many of the research projects target elimination of organic solvents from the sample preparation step to facilitate on-site monitoring and analysis. Several alternative techniques to solvent extraction are investigated including use of coated fibres, packed needles, membranes and supercritical fluids. Also of importance are the efforts in whole column imaging detection for protein and peptide separations in isoelectric focusing. The technology provides for dynamic imaging of the focusing process and better resolution by eliminating the need to mobilize the focused bands prior to detection.
