What are the advantages of UPLC over HPLC?

UPLC (Ultra Performance Liquid Chromatography) typically provides faster analysis times, higher resolution, and improved sensitivity compared to traditional HPLC (High Performance Liquid Chromatography). UPLC systems use smaller particle sizes in stationary phases and higher pressures, leading to better separation efficiency and lower solvent consumption.


How can one determine the appropriate solvent system for TLC?

To determine the appropriate solvent system for TLC (thin layer chromatography), one can consider the polarity of the compound being analyzed and choose a solvent system with a polarity that allows for good separation of the compounds on the TLC plate. Testing different solvent systems with varying polarities can help identify the most suitable one for the specific compounds being analyzed.
