Abstract
A method and device for increasing the loading capacity of a chromatography column through dilution of a mobile phase at the head of the column. A strong mobile phase is provided for dissolving a sample. A sample is injected into the strong mobile phase, and subsequently diluted with a weak mobile phase. The resulting sample-containing weak mobile phase is passed through a chromatography column for retention and separation of the components of the sample.
