Claim 14:
15. The method according to claim 14, wherein during the method the apparatus is in a default position, and when in the default position the apparatus is configured as follows:
the at least one valve of the inert gas portions is closed;
the first multiport valve is set to setting I, wherein two ports of the at least 6 ports of the first multiport valve are connected via two interfaces to the sample circuit vessel and are each linked by one of two ports of the first multiport valve connected to the sample loop, such that the liquid sample of the solution present in the sample circuit vessel is guided via an inlet interface of the two interfaces through the sample loop and via an outlet interface of the two interfaces back to the sample circuit vessel, as a result of which the sample loop is filled with the liquid sample;
the second multiport valve is set to setting I, wherein two ports of the at least 6 ports of the second multiport valve are connected to the reservoir vessel and are each linked to one of two ports of the second multiport valve connected to the solvent loop, such that the solvent is routed with an aid of the pump from the reservoir vessel via the solvent loop back to the reservoir vessel, as a result of which the solvent loop is filled with the solvent;
the fifth multiport valve is set to setting I, wherein a conduit from the first multiport valve and a conduit to the third multiport valve via the fifth multiport valve are connected to one another such that the restriction capillary is bypassed; and
a middle port of the third multiport valve is switched to a port that leads to a residue outlet.
