摘要：

The gas-liquid chromatographic retention behavior of 54 polychlorinated biphenyl (PCB) congeners containing one to ten chlorine atoms was evaluated on a nematic liquid crystal (N,N prime -bis left bracket p-methoxybenzylidene right bracket - alpha , alpha prime //bi-p-toluidine, BMBT). To a first approximation, as anticipated, retention on the liquid crystal appeared to be enhanced with an increasing molecular length-to-breadth ratio for congeners containing the same number of chlorine atoms.
