For separating highly polar compounds on TLC, reversed-phase plates are typically the most effective choice. These plates feature a non-polar stationary phase (such as C18-modified silica), which allows polar analytes to migrate more readily when paired with polar mobile phases like methanol-water mixtures.
Recommended Approach
- Reversed-Phase TLC Plates: Ideal for highly polar compounds that would otherwise remain at the baseline on standard silica gel. They provide better resolution and controlled retention.
- Sorbtech TLC Options: Explore our full selection of TLC plates, including reversed-phase variants, on the dedicated product page: TLC Plates.
Additional Tips
- Use polar solvents (e.g., high water or methanol content) to optimize separation.
- Consider pre-washing plates to reduce background interference for sensitive polar analytes.
- For method development, start with a scouting run using a 60:40 methanol-water system and adjust polarity as needed.
