FAQ
How Is Enrichment Achieved In Low Concentration Sample Components? To enrich sample components that are present at low concentrations, several steps can be followed. You can customize the gradient stages to selectively elute analytes. Using "large" sample volumes in an adsorption-promoting solvent is another useful strategy. Use a "small" collection volume in a desorption-promoting solvent. Use sorbent chemistry that is specific to the analyte and not dependent on the analytical column's chemistry. The chemistry of the solid-phase extraction column should be carefully designed to eliminate the need for any additional sample preparation.
