Question: What is the role of the stationary phase in HPLC?
Options:
To provide a mobile phase
To separate analytes based on their interactions
To inject the sample
To detect the analytes
Correct Answer: To separate analytes based on their interactions

Questions & Step-by-Step Solutions
What is the role of the stationary phase in HPLC?
Step 1: Understand that HPLC stands for High-Performance Liquid Chromatography, a technique used to separate different substances in a mixture.
Step 2: Identify the stationary phase, which is a solid or a liquid that is fixed in place inside the HPLC column.
Step 3: Recognize that the analytes (the substances being separated) pass through the column and interact with the stationary phase.
Step 4: Learn that different analytes interact with the stationary phase in different ways, which affects how quickly they move through the column.
Step 5: Conclude that the role of the stationary phase is to help separate the analytes based on these interactions, allowing for their identification and quantification.
