Abstract
A method and a system for introducing a sample into a mobile phase of a chromatography system is provided. The method includes initially directing the mobile phase directly into a separation unit of the chromatography system, bypassing a sample loop, the mobile phase including a combined solvent, metered from a pressurized first solvent and a second solvent; loading the sample into the sample loop, while the mobile phase continues to be directed directly into the separation unit; pressurizing the sample in the sample loop with the pressurized first solvent, while the mobile phase continues to be directed directly into the separation unit; and switching the sample loop into the mobile phase, thereby introducing the pressurized sample to the separation unit.
