摘要：

Four C-18 columns and a novel amide C-16 column were assessed in the HPLC separation of eight microcystins and nodularin-R. Gradient mobile phases of acetonitrile combined with trifluoroacetic acid, formic acid or ammonium acetate were compared. Special attention was paid to the resolution of four possible coeluting microcystin pairs. Generally speaking, the acidic mobile phases were superior to the ammonium acetate-based mobile phase in terms of resolution and selectivity. The amide C-16 column had the best overall performance and unique selectivity properties. (C) 2001 Elsevier Science B.V. All rights reserved.
