Abstract
The invention relates to an analysis device for compressed gas in a compressed gas cylinder, such as a breathing gas cylinder, for determining gas components, in particular CO, CO2, O2, VOC, SO2, NO, NO2, helium and moisture, having a withdrawal device which can be connected to the compressed gas cylinder, characterized in that the withdrawal device comprises a connection element which is under the pressure of the compressed gas to be analyzed in the compressed gas cylinder and can be connected to a gas treatment device having a gas measuring and evaluation device for determining the desired gas components, the connection element is also pressurized when not connected to the compressed gas cylinder, preferably by means of a shut-off valve, and the gas treatment device and the gas measuring and evaluation device are also configured to monitor and analyze the compressed gas dispensed by the compressor for filling the compressed gas cylinder.
