Zusammenfassung:	A cryogenic liquid sampling system including a chamber having affixed therein a sample pump to proportionally pull a cryogenic liquid sample from an external source to a constant pressure piston accumulator and an enclosure. The enclosure includes a supply port to receive an input stream of a gas, an input port connected to the chamber via a vacuum line, a sample pump port connected to the chamber via a pump line and configured to feed therethrough gas received at the supply port to the sample pump, a vacuum device connected to the input port and configured to generate a vacuum within the chamber by pulling air from the vacuum line, and processing circuitry to control the vacuum device and the sample pump to perform transfer of a cryogenic liquid sample from the external source to an external device.
