Enrichment
On-line sample clean up and enrichment uses a pre-column connected to an analytical column by use of a switching valve. Automation has advantages over offline techniques. On-line analysis improves analytical precision and reduces solvent volumes, since LC pumps meter the flow rates and the volumes of mobile phase passed through both columns. This on-line procedure can enhance productivity by allowing automated, unattended processing of large numbers of samples, using an autosampler and a switching valve connected to the controller of the chromatography.
