| titleOfInvention | Chromatographic method with micellar on-column enrichment |
| abstract | On-column enrichment is provided for a sample (105) having both polar and nonpolar analytes by mixing (302) the sample with surfactant in a polar solvent. The surfactant causes the nonpolar analytes to be incorporated in micelles that dissolve in the polar solvent. The concentration of surfactant is maintained at a level sufficient to maintain the micelles as the mixture is introduced (303) onto the head (204) of a chromatographic column (110). Once sample introduction is completed, the mixture is diluted (304) so that the surfactant concentration drops below that required to maintain the micelles, which thus break up. The analytes are then separated (305) using reverse-phase gradient elution. |
