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.
