Abstract (en)

[origin: WO2018211230A1] An apparatus for analysing the content of at least one contaminant in a liquid cryogen comprising a cylindrical enclosure (E), an annular enclosure (V) arranged around the cylindrical enclosure, means (1, 3, 5) for dividing a flow of liquid cryogen in two, means for delivering a first part (3) of the liquid cryogen to the cylindrical enclosure, means for delivering a second part (5) of the liquid cryogen to the annular enclosure, a pipe (13) connected to the cylindrical enclosure to allow vaporised liquid to pass through, a pipe (6) connected to the annular enclosure to allow vaporised liquid to pass through, a heater (H) for heating the cylindrical enclosure vessel and means (V1) for stopping the delivery of liquid cryogen to the cylindrical enclosure.
