Ultra performance liquid chromatography (UPLC) using small sub-2 mu m particles and high performance liquid chromatography (HPLC) were compared for separation and determination of the most common dietary folates; 5-methyltetrahydrofolate, tetrahydrofolate, 5-formyltetrahydrofolate, 10-formylfolic acid and folic acid. Two UPLC columns-Acquity BEH C(18) and Acquity HSS T3, and two HPLC columns with similar surface chemistry-Xbridge C(18) and Atlantis d18 were tested. When using UPLC, the signal-to-noise ratio could be improved by a factor of 2-50 for different folate derivatives and the run time could be reduced fourfold without sacrificing separation efficiency. The applicability of UPLC to real food samples was demonstrated
