Summary

This application note by Hormoz Mazdiyasni of Teledyne ISCO highlights the benefits of dry sample loading for improving resolution in normal phase flash chromatography. The study compares liquid injection techniques with two dry sample preparation methods: pre-packed solid load cartridges and sample adsorbed onto Celite.

Key Findings:

- Liquid Injection vs. Dry Loading: Volume overloading through direct injection of dissolved samples causes significant band broadening, degrading resolution. Dry loading, especially after removing the polar diluent, enhances separation.

- Pre-Packed Silica Cartridges: Using RediSep 5g or 12g normal phase columns with pre-packed silica cartridges significantly improves peak resolution and separation compared to liquid injection.

- Celite Adsorption: Adsorbing the sample onto Celite before placing it in a solid load cartridge provides some improvement, but less than with pure silica due to Celite's lack of retentive properties.

Method Parameters:

- Instrumentation: Teledyne Isco CombiFlash Companion System
- Column: Teledyne Isco RediSep 12g Normal Phase Column
- Wavelengths: 254nm (detection), 280nm (monitoring)
- Sample: 280mg mixture of methyl-4-hydroxybenzoate and 2-amino-5-chloropyridine
- Mobile Phase: Hexane/Ethyl Acetate gradient
- Flow Rate: 30mL/min
- Equilibration Volume: 100mL
