Frequently Asked Questions (FAQs):
- What is the principle behind HPLC?
HPLC separates compounds based on their interaction with a stationary phase and a mobile phase. The stationary phase is typically a solid or liquid immobilized on a solid support, while the mobile phase is a liquid or gas that flows through the column. Compounds in the sample interact differently with the stationary and mobile phases, causing them to elute from the column at different times.
- What are the advantages of HPLC?
HPLC offers several advantages, including high resolution, sensitivity, and versatility. It can separate a wide range of compounds, including small molecules, large molecules, and ions. Additionally, HPLC is a relatively fast technique, and it can be automated, making it suitable for high-throughput analysis.
- What are the limitations of HPLC?
HPLC can be expensive to purchase and maintain. Additionally, it requires skilled operators, and the analysis can be time-consuming. Furthermore, HPLC is not suitable for analyzing volatile compounds or compounds that are unstable in the mobile phase.
