高分辨核磁共振仪的气流系统是旋转样品提高分辨率必不可少的,此外,它还供给探头系统的冷却,特别是带走测试~(13)C样品~1H去耦(~(13)C—{~1H})时高功率所产生的热量,否则会使样品温度上升使分辨率变坏或破坏样品,甚至可能烧坏去耦线圈,造成永久性的损坏,为此在核磁共振仪中一般部有保护装置,一旦气路故障,立即自动的切断有关电路,确保探头的安全。
High-resolution NMR airflow system is essential for rotating the sample to improve resolution, in addition, it also provides cooling for the probe system, especially for take-away test ~ (13) C sample ~ 1H decoupling (~ (13) C - {~ 1H}), the heat generated by high power, otherwise it will make the sample temperature rise to make the resolution deterioration or damage to the sample, and may even burn the decoupling coil, causing permanent damage, for which in the nuclear magnetic resonance General Department of protection, once the gas path failure, immediately automatically cut off the circuit to ensure the safety of the probe.
