FIELD: technological processes, chemistry.
SUBSTANCE: operation of purified xenon condensation is carried out in balloon of end product accumulation with further removal of air components from it be means of working volume vacuumising at the temperature of minus 196°C to residual pressure that exceeds balanced pressure of xenon 1.5...2 times. Vacuumising of working volume of accumulation balloon is stopped, when value of accumulation balloon air components quenching reaches not more than 2+1×10-3 mm of mercury column/hour. Further determination of quenching value is carried out after performance of balloon vacuumising operation during at least 1 hour.
EFFECT: ultrahigh quality of xenon purification, exclusion of end product losses at minimum working house spent and power consumption.
