Claim 0:
1. A titration apparatus comprising:
a titration measuring cell having a titration vessel;
a first fluid line connected to a first liquid supply;
a second fluid line opening into the titration vessel;
a first pump configured to transport liquid through the second fluid line into the titration vessel;
a valve device;
a temporary storage container arranged in a fluid path between the first pump and the valve device and configured as a fluid line; and
a third fluid line connecting the first pump to the temporary storage container and filled with a working liquid in a section adjacent to the first pump;
wherein the valve device is configured to selectively block or unblock the first fluid line for fluid transport through the first fluid line into the temporary storage container using the first pump, and
wherein the valve device is configured to selectively block or unblock transport of liquid from the temporary storage container through the second fluid line using the first pump;
and wherein the titration apparatus further comprises:
a fourth fluid line opening into the titration vessel;
a second pump configured to convey a volumetric solution from a volumetric solution supply and to transport the volumetric solution taken from the volumetric solution supply through the fourth fluid line into the titration vessel; and
an electronic controller configured to control the first and the second pumps and the valve device in order to convey a liquid from the first liquid supply into the temporary storage container,

in order to transport the liquid from the temporary storage container via the second fluid line into the titration vessel, and
in order to transport the volumetric solution from the volumetric solution supply via the fourth fluid line into the titration vessel in order to carry out a titration.
