二甲基锌中的含氧量对二甲基锌下游产品处延片及最终的光电器件或高频器件有着至关重要的影响，因此氧含量的测定是界定二甲基锌品质优劣的一个重要的指标。 核磁共振可以将样品在惰性气氛保护下密闭在核磁管内，保证了水、氧、空气的隔绝，所以目前国际上普遍使用核磁共振仪进行二甲基锌有机氧含量的检测。二甲基锌中的氧是以甲氧基形式存在产品中的。核磁共振仪通过甲氧基出峰位移处是否有质子峰来确认二甲基锌中是否含甲氧基。将待测物置于无水无氧条件下取样，加入氘带试剂（氘带试剂经无水处理），密封胶密封后，取出，使用400M核磁共振仪检测，得到核磁氢谱图。

The oxygen content of dimethyl zinc has a vital influence on the downstream products of dimethyl zinc wafers and the final photoelectric devices or high-frequency devices, so the determination of oxygen content is an important index to define the quality of dimethyl zinc. Nuclear magnetic resonance can sample in inert atmosphere under the protection of sealed in the nuclear magnetic tube, to ensure the isolation of water, oxygen, air, so currently the international universal use of nuclear magnetic resonance instrument for dimethyl zinc organic oxygen content detection. The oxygen in dimethyl zinc is present in the product in the form of methoxyl. The nuclear magnetic resonance apparatus confirms whether dimethyl zinc contains methoxyl by checking whether there is a proton peak at the shift of methoxyl peak. The object to be measured was placed in anhydrous and oxygenless conditions for sampling, deuterium strip reagent was added (deuterium strip reagent was anhydrous), sealed with sealant, and then the nuclear magnetic tube was removed, detected by 400M nuclear magnetic resonance instrument, and the nuclear magnetic hydrogen spectrum was obtained.
