Start from separation evidence
Preparative scale-up should begin with an analytical or pilot method.
Target compound and impurities
Required purity and recovery
Stationary and mobile phase
Retention, selectivity, and loading study
Plan preparative LC scale-up by target purity, sample load, flow, pressure, column, pump, detector, fraction collection, and solvent handling.
Direct Answer
Preparative scale-up should begin with an analytical or pilot method.
Target compound and impurities
Required purity and recovery
Stationary and mobile phase
Retention, selectivity, and loading study
Pump, detector, column, tubing, and collector must operate as one flow path.
Required flow and pressure
Column diameter and bed length
Detector flow cell and signal range
Fraction-collection logic and vessel capacity
Productivity depends on more than the instrument purchase.
Solvent consumption and recovery
Sample preparation and injection
Cleaning and column packing
Installation, training, and spare parts
Analytical chromatogram
Sample load and concentration
Purity and recovery target
Solvent system
Flow, pressure, and column
Detector and collector
Daily production target
These products are relevant starting points; final suitability depends on the complete method and configuration.
