Study Notes
Supercritical Fluid Chromatography (SFC)
- Uses a supercritical fluid as the mobile phase.
Analyzing Molecules
- SFC is used to analyze and purify non-polar to moderately polar molecules.
- These molecules are often thermally labile, chiral, or have low volatility.
Alternative Names
- SFC is also known as High-Pressure Chromatography.
Industrial Applications
- The primary application of SFC in the industry is for purification and analysis of molecules.
- This is especially true for the pharmaceutical industry.
Instrumentation
- The entire chromatographic flow path must be pressurized in SFC.
Principles
- SFC operates based on the principles of adsorption chromatography.
- Separation occurs due to differences in the affinity of analytes for the stationary phase.
Pharmaceutical Applications
- The primary use of SFC in the pharmaceutical industry is for chiral separation and purity analysis.
Types of Molecules
- SFC is commonly used to separate chiral molecules, complex natural products, and polymeric molecules.
Supercritical State
- The supercritical state is a condition where liquid and gas properties converge.
- This state is characterized by high density and solubility, and low viscosity and surface tension.
Column Selection
- SFC columns are typically packed with stationary phases like silica or immobilized polysaccharide.
