Peter Uden
Peter Uden became an Emeritus faculty of the University of Massachusetts in 2004. In honor of his distinguished career and his warm mentoring of over 100 graduate students, a celebration was held on July  17 and 18 to honor Peter.

This page contains images and documents for Peter's students and to document his career.

Keywords :
Analytical Chemistry. Gas chromatography; volatile metal complexes and organometallic compounds, pyrolysis - GC of polymers and geochemical materials; GC-Mass spectroscopy; separation methods; trace analysis and speciation in environmental, petrochemical and food/ agricultural materials; high pressure liquid chromatography; supercritical fluid chromatography and extraction; capillary zone electrophoresis; clinical and pharmaceutical analysis. Environmental studies of humic reactions and chlorination products.

Principal Research Interests: The interfacing of gas and liquid chromatography with atomic plasma emission spectroscopy (C-AED) for element specific detection has been applied to simultaneous detection of fluorine and oxygen in freon substitutes, phosphorus and boron specific detection, and study of tin, manganese, vanadium, nickel, copper, palladium, and platinum organometallics and metal complexes in crude oils. Development of analytical methods for organomercurials, organotin and organolead compounds in reference materials is caried out in collaboration with the National Institute of Standards and Technology (NIST). GC-AED speciation studies of volatile organo-selenium compounds in foodstuffs using head-space sampling are iapplied in nutritional and clinical studies; HPLC element specific detection of selenium amino acids is carried out by inductively coupled plasma mass spectrometry. Speciation of organometallics in marine materials ranging from plankton to higher mammals is being carried out. Multidimensional gas chromatography is applied in petrochemical and environmental areas. SFE (supercritical fluid extraction ) is used for oil and agrochemical extraction from soils and pharmaceuticals.
Pyrolysis studies are carried out on coals and ocean sediment cores, interfaced GC-MS and GC-AED being used extensively in this work. Environmental studies of trace halo-organics in drinking water and humic materials have a major emphasis on nitrogen compounds present.
Diode-array detection for HPLC is used to examine chemical species in the blood and urine of premature new-born infants. Capillary zone electrophoresis (CZE) has been applied to studies of the proteins, polysaccharides and also oxalate and other dibasic anions in clinical and industrial environments.
