Parallel supercritical fluid chromatography/mass spectrometry system for high-throughput enantioselective...

Area of Science:

• Analytical Chemistry
• Chromatography
• Mass Spectrometry

Background:

• Enantioselective separation is critical in pharmaceutical development.
• Traditional method development for chiral separations is often time-consuming and labor-intensive.

Purpose of the Study:

• To develop a high-throughput, automated system for enantioselective chromatographic method development and optimization.
• To streamline the process of identifying optimal conditions for separating enantiomers.

Main Methods:

• An automated parallel four-column supercritical fluid chromatography (SFC)/MS system was designed.
• Initial screening utilized four chiral SFC columns simultaneously across various buffer conditions.
• Optimization was performed on a single column, controlled by custom software (IPOCSS) for automated experimental selection based on user-defined criteria.

Main Results:

• The automated system enabled fully automated, user-independent screening and optimization.
• The IPOCSS software effectively monitored runs, processed data, and selected experiments to optimize enantioseparation.
• Successful application to enantioseparations in drug discovery support was demonstrated.

Conclusions:

• The developed automated parallel SFC/MS system offers a streamlined and high-throughput solution for enantioselective method development.
• This intelligent software-controlled approach significantly accelerates the optimization of chiral separations.
• The system is a valuable tool for supporting drug discovery efforts requiring efficient enantiomer separation.
