Kiinteäfaasikoekromatografia

Kiinteäfaasikoekromatografia, often abbreviated as SFC, is a type of chromatography that utilizes a solid stationary phase and a liquid mobile phase. The principle behind SFC is the separation of components in a sample based on their differential partitioning between the stationary and mobile phases. The stationary phase is typically a porous solid material, such as silica gel or alumina, packed into a column. The mobile phase, a liquid solvent or mixture of solvents, is pumped through the column, carrying the sample with it. As the sample moves through the column, different components interact with the stationary phase to varying degrees. Components that interact more strongly with the stationary phase will move slower, while those that interact less strongly will move faster. This difference in migration speed leads to the separation of the sample into its individual constituents, which can then be detected as they elute from the column. SFC is a versatile technique used in various analytical and preparative applications, including the analysis of pharmaceuticals, environmental samples, and natural products. The choice of stationary and mobile phases is crucial for achieving optimal separation and is dependent on the properties of the analytes being separated.
