A method for leak monitoring a high-pressure vessel includes the following steps: (a) pumping and compressing a liquefied gas via a pump from a source of liquefied gas so as to obtain a pressure of 500 to 1000 bar, (b) vaporizing the liquefied gas, (c) compressing a tracer gas to a pressure of 500 to 1000 bar, (d) mixing the vaporized liquefied gas obtained in step (b) with the compressed tracer gas obtained in step (c) in a buffer tank, (e) filling the high-pressure vessel to be monitored with the mixture obtained in step (d), then (f) checking for tracer gas leaks on the high-pressure vessel to be monitored.
