The mobile phase consisted of 0.1% methanoic acid in methanol (mobile phase A) and acetonitrile containing 0.1% formic acid (mobile phase B).
The mobile phase buffer A contained [H.sub.2]O and 0.1% methanoic acid. The mobile phase buffer B contained acetonitrile and 0.1% methanoic acid, 120 min linear gradient elution, and flowed at 1 [micro]L/min.
Mobile phase: A, [H.sub.2]O (0.2% methanoic acid), B, CH3CN; gradient: 5-30% B linear in 10 min; 30-40% B linear in 20min; 40-80% B linear in 20min; isocratic on 80% B for 10 min, flow rate: 0.8ml:min; Detection wavelength: 350 nm; injection volume: 20 [micro]l.
