2. Phosphate buffer solution, c = 0,01 mol/l.
3. Ammonium acetate buffer solution, approximately 0,25 mol/l.
4. Acetate buffer solution, c = 0,01 mol/l, pH = 6,0.
5. Mix 5 ml of phosphate buffer solution (3.7) with 95 ml of methanol (3.5).
6. Mixture of phosphate buffer solution (3.7) and methanol (3.5), 5+95 (V+V)
7. Mixture of acetate buffer solution (3.9) and acetonitrile (3.2), 825 + 175 (v+v)
8. Add 2 ml of the pH 3,5 buffer solution (paragraph 2.1.4); mix.
9. HPLC mobile phase, phosphate buffer-methanol solution 5 + 95 (V + V).
10. Mix 825 ml of acetate buffer solution (3.9) with 175 ml of acetonitrile (3.2).
