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.
