Analytical/Preparative Automatic Switching System
■ Improves Efficiency for Investigating Conditions and Scaling Up
The process to scale up to preparative work is complex:
Investigate separation conditions with an analysis column and conditions to increase load
↓
Check reproducibility of the chromatogram pattern with a preparative column
↓
Investigate fractioning conditions with a preparative column / Purity inspection including repeated chromatography with an analysis column
↓
Automated continuous preparation with a preparative column
The Analytical/Preparative Automatic Switching System supports both the analytical and preparative scales, making it easy to investigate the preparative conditions. It also reduces the consumption of mobile phase solvent and sample and saves on operator training costs.
As an example, Fig. 1 shows the system overview and flow diagram of a system configured with an LC-8A pump.

Failure to ensure accurate matching between the preparative sample and its chromatogram, or between a peak on the chromatogram and the vial from which the peak was fractioned (target component fraction), results in wastage of the compound obtained and can significantly affect the next stages. Open Solution open access-compatible software for LCMS/HPLC displays links between the vial rack diagram, preparative results, and fractioned vial to provide accurate and instant access to the preparative results.
