ABSTRACT:
A process for programming of field decay or of increase of channel flow in field-flow fractionation which imparts improved uniformity of fractionating power which comprises an improvement in the field-flow fractionation technique which involves varying one of the parameters that affect the interaction of the sample components with the field and fluid medium in order to reduce separation time and better equalize component separation. These parameters include decreasing the field strength according to a specific power equation, or increasing the flow rate according to another power equation, or use of both parameters together.
