Abstrakty
W artykule opisano zastosowanie mikroemulsyjnej chromatografii elektrokinetycznej (MEEKC) do ilościowego oznaczania witaminy E w postaci octanu α-tokoferolu. Analizę wykonano za pomocą aparatury do elektroforezy kapilarnej, zaopatrzonej w detektor z matrycą diodową. W kapilarze stosowano mikroemulsję o składzie: 10% (w/w) SDS, 6,6% (w/w) 1-butanolu, 0,8% (w/w) n-oktanu, 12,5% (w/w) 2-propanolu, 40% (w/w) buforu fosforanowego o pH=2,5 oraz 30,1% (w/w) wody demineralizowanej. Oznaczanie ilościowe witaminy E wykonano metodą wzorca zewnętrznego z wykorzystaniem oprogramowania 32 Karat ver. 8.0 Beckman Coulter Inc. Dodatkowo wykonano oznaczanie ilościowe witaminy E metodą ultraszybkiej chromatografii cieczowej (UFLC) w celu porównania wyników z metodą MEEKC.
In the present work microemulsion electrokinetic chromatography (MEEKC) was applied for quantitative determination of vitamin E in α-tocopherol acetate form. Capillary electrophoresis system with diode array detector was used to perform the analysis. Microemulsion consists of: 10 % (w/w) SDS, 6.6 % (w/w) 1-butanol, 0.8 % (w/w) n-octane, 12.5 % (w/w) 2-propanol, 40% (w/w) phosphate buffer with pH=2.5 and 30.1 % (w/w) demineralized water, was used in capillary. The quantitative determination of vitamin E was performed with the external standard method with the use of the 32 Carat ver. 8.0 software from Beckman Coulter Inc. Additionally the quantitative determination of the vitamin E by ultrafast liquid chromatography (UFLC) method was performed for the purpose of the comparison of results with the MEEKC method.
