Abstract
The present invention relates to an apparatus for the simultaneous analysis of at least two samples by the field-flow fractionation method, where the apparatus has at least the following elements:a) a source of a defined liquid stream, preferably a pump,b) at least two separation channels, each with at least one inlet and each with at least one outlet for passing the at least two samples through in each case one of the at least two separation channels,c) at least one controllable unit which is connected to the at least two separation channels via their at least one outlet each, and which can pass on the at least two samples, which can be passed through in each case one of the at least two separation channels, separately from one another to at least one unit downstream of the controllable unit.
