Guidelines for Preparative Scale and Maximum Load
The figure at right shows the guidelines for total component capacity with a 250 mm long column when the target component is highly soluble in the mobile phase, separates from impurities, and ions are suppressed. For isocratic elution, in principle, the total component capacity is proportional to the column volume.

• This solvent delivery unit can handle flow rates ranging from those used in analytical scale to those used in semi-preparative (up to 10 mL/min).
• High-precision analysis is possible even in the semi-micro flow-rate range.
