Abstract
A new way of cross-linking glass capillary columns with dihydroxy-substituted saturated urushiol crown ether stationary phase is described. The columns were evaluated by determining the column efficiency, phase transition temperature, thermal stability and polarity. It was shown that they have good chromatographic characteristics and unique selectivity in separating phenols, nitro compounds and monsaccharides. The average polarity of these columns was comparable to those of SE-52 and FFAP. The mechanism of separation is discussed.
