Zusammenfassung:	The present disclosure describes an apparatus, method, and system of regulating a detector flow of a field flow fractionator. In an embodiment, the apparatus includes (1) a detector flow meter, where the detector flow meter is configured to measure a detector flow from the field flow fractionator, (2) a channel pressure meter, where the channel pressure meter is configured to measure a channel pressure of the field flow fractionator, (3) at least one control valve, where an inlet of the at least one control valve is connected to an outlet of the channel pressure meter, (4) where the detector flow meter is configured to set a channel pressure set point of the channel pressure meter, and (5) where the channel pressure meter is configured to actuate the at least one control valve to maintain a channel pressure of the field flow fractionator at the channel pressure set point.
