Abstract
A splitter for a pressurized primary flowstream of a mobile phase is provided. The splitter comprises a first splitting stage that divides the primary flowstream between a major split flowstream and a minor split flowstream by means of a first and a second restrictive flow element; a first dilution stage that combines a dilution flow source with the minor split flowstream to create a diluted minor flowstream; a second splitting stage that divides the diluted minor flowstream between a secondary major diluted flowstream and a secondary minor diluted flowstream by means of a third restrictive element in the secondary minor diluted flow stream; and a second dilution stage wherein a conditioning flow source conditions the secondary minor diluted flow stream after the third restrictive element prior to outlet of the secondary minor diluted flowstream from the splitter.
