%X Wide bore (> or = 0.5 mm i.d.) packed capillary liquid chromatographic columns with conical end were designed and evaluated. It was found that the column efficiency was 30%-50% higher than that of the packed capillary columns with conventional end connection at optimal flow rate, and was twice as much as that at reduced flow rate of 10-15. The chromatographic peak symmetry and the van Deemter curve of the novel shape column were also improved substantially. Fast analysis of PAHs is demonstrated.
