Abstract
The preparation of graphite layer open tubular (GLOT) columns is descr ibed together with their application to the analysis of priority pollu tants and polar compounds such as alcohols, free carboxylic acids, ali phatic amines and phenols at the sub-nanogram level. A specific applic ation of GLOT columns is for the direct analysis of aqueous solutions avoiding solvent extraction procedures. Several chromatograms of criti cal separations are reported together with calibration curves. A study of the reproducibility of column preparation is reported in terms of the standard deviation of the capacity ratio and of the minimum HETP o btained.
