The Studies on the Use of Calix[4]arene in Capillary Electrophoresis

Abstract

Abstract: The behavior of water-soluble p-sulfonic calix[4]arene in capillary electrophoresiswas first reported. Amixture of nitrophenol isomers was completely separated using only 3 mmol/Lcalixarene. The efficiency of 3. 0 × 10⁵ plates/m was achieved and the detectionlimits were 33. 6, 21. 8 and 16. 2 pg for o-, m- and p- nitrophenol respectively under thecon-ditions fused-silica capillary(44 cm ×50 μm i. d., effective length 37 cm), phosphate buffer(50 mmol/L, PH5.0), 25℃, 14 kV, 275 nm and 1 s vacuum load.
