Glossary Reverse Phase High Performance Liquid Chromatography

technique separating mixture components using non-polar stationary phase

Reverse Phase High Performance Liquid Chromatography (RP-HPLC) is a technique used to separate, identify, and quantify components in a mixture. It involves a non-polar stationary phase and a polar mobile phase, meaning that non-polar compounds in the mixture will interact more with the stationary phase and thus move more slowly through the system, allowing for effective separation based on polarity.
