Abstract
A closed &Dgr;P -installation is disclosed for the potential-independent control of the pressure difference for continuous column tests under high hydrostatic pressure, as well as a pressure difference control process useful in particular for carrying out migration tests in pressure columns. By coupling two potential bottles into a closed vessel system, the gas or fluid pressure required to carry out the continuous column tests can be regulated at any desired height independently of outer influences. The pressure difference required to move the liquid is adjusted by setting the potential bottles at predeterminable heights.
