Abstract Ultra Performance Liquid Chromatography (UPLC) is a relatively new technique giving new possibilities in liquid chromatography, especially concerning decrease of time and solvent consumption. UPLC chromatographic system is designed in a special way to withstand high system back-pressures. Special analytical columns UPLC Acquity UPLC BEH C(18) packed with 1.7 microm particles are used in connection with this system. The quality control analyses of four pharmaceutical formulations were transferred from HPLC to UPLC system. The results are compared for Triamcinolon cream containing trimacinolone acetonide, methylparaben, propylparaben and triamcinolone as degradation product, for Hydrocortison cream (hydrocortisone acetate, methylparaben, propylparaben and hydrocortisone degradation product), for Indomethacin gel (indomethacin and its degradation products 4-chlorobenzoic acid and 5-methoxy-2-methylindoleacetic acid) and for Estrogel gel (estradiol, methylparaben, propylparaben and estrone as degradation product). The UPLC system allows shortening analysis time up to nine times comparing to the conventional system using 5 microm particle packed analytical columns. In comparison with 3 microm particle packed analytical columns analysis should be shortened about three times. The negative effect of particle decrease is back-pressure increase about nine times (versus 5 microm) or three times (versus 3 microm), respectively. The separation on UPLC is performed under very high pressures (up to 100MPa is possible in UPLC system), but it has no negative influence on analytical column or other components of chromatographic system. Separation efficiency remains maintained or is even improved. Differences and SST parameters, advantages and disadvantages of UPLC are discussed.
