Dr. Bertsch's research interests lie in the general area of chromatography,
in particular GC/MS and interfacing disciplines. Special areas
of interest with ongoing research are:
Forensic chemistry. Development of GC/MS based methods
for accelerant analysis.
Environmental analysis. Investigation of volatiles from
point sources and industrial processes.
Pheromones. Insect and mammalian pheromone systems, analysis
and methodology development.
Pyrolysis-GC. Application to bacterial classification,
biomedical problem, chemical analysis, high polymers, forensic analysis.
Natural products chemistry. Determination of biologically
active phytochemicals in plants.
Automated pattern recognition. Chemometrics, applied to
all problems of practical interest.
Two-dimensional GC. Methodology development for heart-cutting,
adjustment of phase selectivity and automated analysis
Recycle Chromatography. Peak shape modeling, applied to
Dr. Bertsch is the editor of the Journal of High Resolution Chromatography
and Chromatographic Methods, and he is coorganizer of the International
Symposia on Capillary Chromatography and Environmental Analysis.
