6 Questions
What is HPLC and what is its purpose?
HPLC is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture.
What is HPLC?
A technique used in analytical chemistry to separate, identify, and quantify each component in a mixture
How does HPLC work?
HPLC relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material. The components in the sample interact differently with the adsorbent material, leading to separation as they flow out of the column.
What is the active component of the column in HPLC?
A solid adsorbent material
What is the mobile phase in HPLC and how does it affect the separation process?
The mobile phase in HPLC is a mixture of solvents. The composition and temperature of the mobile phase play a role in the separation process.
What kind of interactions occur between sample components and adsorbent in HPLC?
Physical interactions, such as hydrophobic, dipole-dipole, and ionic
Study Notes
- HPLC is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture.
- It relies on pumps to pass a pressurized liquid solvent containing the sample mixture through a column filled with a solid adsorbent material.
- The components in the sample interact differently with the adsorbent material, leading to separation as they flow out of the column.
- HPLC has various applications in manufacturing, legal, research, and medical fields.
- The active component of the column is the adsorbent, which is typically a granular material made of solid particles.
- The pressurized liquid is a mixture of solvents and is called the "mobile phase".
- The composition and temperature of the mobile phase play a role in the separation process.
- Interactions between sample components and adsorbent are physical in nature, such as hydrophobic, dipole-dipole, and ionic.
- Chromatography is a mass transfer process involving adsorption.
- HPLC was formerly referred to as high-pressure liquid chromatography.
