Abstract

See full text

A method of sterilizing an object with atomic nitrogen from a nitrogen plasma comprises the steps of positioning the object in a sterilization chamber, and conditioning the object present in the chamber. The step of conditioning includes a first stage of injecting atomic nitrogen into the chamber, during which a first concentration of atomic nitrogen in the chamber is imposed, a suction stage performed after the first injection stage, during which the chamber is evacuated, and a second stage of injecting atomic nitrogen into the chamber that is performed after the suction stage, during which a second concentration of atomic nitrogen is imposed in the chamber. The method further comprises a sterilization step of sterilizing the object, performed after the conditioning, and includes injecting atomic nitrogen into the chamber, during which step a concentration of atomic nitrogen in the chamber is imposed that is greater than the first and second concentrations.
