FAQ
Why Is It Difficult To Get Reproducible Retention Times In Normal Phase Chromatography? The strong dependence of the retention on the content of highly polar mobile phase constituents, especially water, causes variability in retention time in normal phase HPLC. Small quantities will always be dissolved even in very apolar solvents even without any addition of water. Additionally, bare silica is extremely hygroscopic, causing water to be adsorbed on the surface. Therefore, the water content in a normal phase system is rarely controlled and can vary significantly.
