  • Pittcon 2013®: Developments in Liquid Chromatography

    Monday, May 13, 2013
    Technical Article
    Robert L. Stevenson, Ph.D.
    The first commercial liquid chromatograph was probably an amino acid analyzer. These ion exchange chromatographs were so specialized that they had almost no impact on chemical analysis outside of ... read more

  • The Future of GC Instrumentation From the 35th International Symposium on Capillary Chromatography (...

    Thursday, September 01, 2011
    Technical Article
    Robert L. Stevenson, Ph.D. Ronda Gras Milton Lee
    Instrumentation has a life cycle. Gas chromatographs are mature, so the cycle is probably 10–12 years. read more
