The invention relates to a method and to a device for gassing, wherein a gas mixture of a gassing agent and of a cryogenic liquid is vaporized in that the mixture, which is pressurized in a storage container, is guided through a pressure reducing valve, so that the mixture is vaporized completely and the steam is supplied for gassing goods. According to a first aspect of the instant invention, the temperature of the mixture is maintained in the storage container such that it forms an overcritical fluid. Through this, a distillation of the gassing agent is avoided. According to a second aspect of the instant invention, the vaporized mixture is diffused by adding compressed air and the ratio between mixture and the compressed air is adjusted by means of replaceable screens and/or adjustable pressure reducing valves. Through this, the ratio between the mixture and the compressed air can be varied freely.
