Fig. 3From: Purification of high purity docosahexaenoic acid from Schizochytrium sp. SH103 using preparative-scale HPLCEffect of mobile phase composition on DHA purity, column backpressure and retention time using water (0–10%, v/v) in methanol at various concentrations. The mobile phase velocity (0.5 mL/min) was held constant across all trials. Filled circle—DHA; filled square—retention time; filled triangle—column back pressure. Error bars (± SDs) are shown when larger than the symbolBack to article page
