Response to the 2003 Gas Chromatography User Study-Trends in Column Use and Techniques

摘要

Gas chromatography (GC) is a mature separation technique, and most analytical laboratories, especially those analyzing organic compounds,have at least one GC instrument. Users of high performance liquid chromatography (HPLC) columns are surveyed frequently by LCGC North America and, in the past, analyzing the results of these studies has allowed me to note current trends. LCGC has not surveyed GC users to the same extent. In fact, the magazine has surveyed GC users about their column usage only three times - in 1990 (1), in 1995 (2), and is 2003 (3).
