Q2. What is HPLC and principle
Ans. 
HPLC stands for High Performance Liquid Chromatography. It is a technique used to separate, identify, and quantify components in a mixture.
• HPLC involves a sample being dissolved in a solvent and then pumped through a column packed with a stationary phase.

• The different components in the sample interact differently with the stationary phase, causing them to separate based on their properties.

• The separated components are ...read more
