The experiments were made possible by a novel, one-layer iontrap cooled to minus 269 C (minus 452 F) with a liquid helium bath.
实验利用了一种单层离子势阱,并将其浸在液氦浴中冷却到零下269摄氏度。

Analytical advantages of high sensitivity, high selectivity and rapid response time make gas chromatography-toroidal iontrap mass spectrometry (GC-TMS) a preferred detection technique.
