Figure 1-6. Ultrafast separations carried out in HT-ultrahigh-pressure liquid chromatography. (A) Isocratic separation of various preservatives and uracil. Column: Acquity bridged ethylsiloxane/ silica hybrid (BEH) C18 (50 x 2.1 mm I.D., 1.7 um); mobile phase: water-acetonitrile (50:50%, v/v); flow rate: 1800 uL/min; temperature: 90 oC; (B) Gradient separation of several doping agents. Column: Acquity BEH Shield RP18 (50 x 2.1 mm I.D., 1.7 um); mobile phase: 0.1% formic acid in water-0.1% formic acid in acetonitrile; flow rate: 1800 uL/min; temperature:
