1. An apparatus for automated sampling, comprising:
a sample circuit comprising a first multiport valve having at least 6 ports, a first feed conduit, a first drain conduit, and a sample loop, wherein the sample circuit is configured to withdraw a liquid sample from a sample circuit vessel containing a solution,
a solvent circuit comprising a reservoir vessel for a solvent, a second multiport valve having at least 6 ports, a pump, a second feed conduit, a second drain conduit, and a solvent loop, wherein the solvent circuit is configured to add the solvent for dilution of the liquid sample;
at least one sample vessel, wherein the at least one sample vessel is configured for the liquid sample to be routed into;
a sample distribution unit comprising a third multiport valve having at least 3 ports and at least one conduit connected to the at least one sample vessel, wherein the liquid sample taken from the sample circuit vessel via the at least one conduit can be routed into the at least one sample vessel;
a pressure regulation unit configured to bring the liquid sample to ambient pressure, wherein the pressure regulation unit comprises a fifth multiport valve having a restriction capillary wherein this the fifth multiport valve is disposed between the first multiport valve and the third multiport valve: and
inert gas portions in which there is an inert gas, wherein the inert gas portions comprise at least one valve and a third feed conduit both operational connected to the second multiport valve, and a third drain conduit operationally connected to the third multiport valve;
and a plurality of conduits via which the first multiport valve, the second multiport valve, the third multiport valve, and the fifth multiport valve, are connected.
