Abstract
The present invention relates to a method for replacing a sterilizing agent in a gaseous form with an inert gaseous material in a package to be aseptically or sterile filled, wherein the inert gaseous material is selected in such a way that it has a temperature at addition which provides a volume, which is smaller than a volume of sterilizing agent to replace at the temperature at which the sterilization takes place.

Method for replacing a sterilizing agent in gaseous form with an inert gaseous material in a package to be aseptically or sterile filled, wherein the inert gaseous material is selected in such a way that it has a temperature at addition, which provides volume, which is smaller than the volume of sterilizing agent to replace at the temperature, at which the sterilization takes place, whereby the smaller volume of inert gas expands when the temperature is raising to the temperature of the sterilizing gas.
