    Biography

      Jim McCurry is a senior applications chemist specializing in analytical chemistry measurements using gas chromatography (GC) and mass spectrometry (MS).  His current work is in multidimensional GC, trace analysis in complex matrices, and fast GC, and GC/MS.  He is a member of the American Chemical Society and the American Society of Testing and Materials (ASTM).  Jim holds a B.S. in Biochemistry from the University of Scranton and an M.S. and Ph.D. in Chemistry from Lehigh University.


    Abstract

    Helium supply problems and price increases have again impacted analytical chemists’ ability to run high resolution gas chromatography methods. Until new sources of helium can be found, laboratories can continue operation by combining two techniques; conversion to alternative carrier gases and conservation of helium resources.  This presentation will discuss when and how to use alternative carrier gases and when helium is required, new technologies to continue helium use with automated conservation.
