The whole analysis was completed on a C〓 column in 18min at a flow rate of 0.5 ml/min, with the mobile phase of methanol-water (93: 7, v: v) containing 75 mmol/L TEOLA and 200 mmol/L HAc, or with the mobile phase of ethanol-water (90: 10, v: v) containing 25 mmol/L TEOLA and 200mmol/L HAc pumped at 0.25ml/min. Compared with the methanol system, the ethanol system was a better candidate for the separation of thulium porphyrin complexes in view of selectivity.
在C〓分析柱(5μm,2.5×150mm)上,流动相为:甲醇:水=93:7(v/v内含75mmol/L三乙醇胺和200mmol/LHAc),流速为0.5ml/min和流动相为:乙醇:水=90:10(v/v,内含25mmol/L三乙醇胺和200mmol/L HAc),流速为0.25ml/min,均能使六个铥卟啉配合物在18min内得到有效的分离,相比之下,乙醇体系对铥卟啉配合物更具有分离选择性。
