Lor analyses, two sets of HPLC conditions were used, depending on whether UV (285 nm) or MS (electrospray ionization on a triple quadrupole system) was to be used for detection. Lor MS detection, analyses were conducted using a 125 x 4 mm (5 pm) Lichrospher 60 RP-Select B column. Eluent A was 800 ml water/200ml acetonitrile/3.08 g ammonium acetate adjusted to pH 6.5 with acetic acid. Eluent B was 500 ml water/500ml acetonitrile/1.93 g ammonium acetate adjusted to pH 6.5 with acetic acid. The gradient was run at 0.5ml/min as follows from 0-25.0 min, 100% A from 25.0-35.0 min, 100% A-100% B from 35.0-45.0 min, 100% B from... [Pg.358]
