Oxidation optimization. Graph a shows the hybridization intensity features on a microarray synthesized with a long oxidation step in each cycle (A), a long oxidation step in each cycle but no helium drying step (B), a short oxidation step in each cycle (C), and a single final oxidation (F). Values below the expected trend (dotted line) indicate worse results. In Graph b, bars A, B and C are short oxidations steps in each cycle and F is a single final oxidation
