【摘要】 本工作在2D DOSY实验技术开发的基础上,探究了NMR在不分离或非全分离条件下对混合样品中的组分进行筛选性鉴别中的应用;实验结果表明:在特定条件下DOSY可以对复杂体系中的组分进行"虚"分离,使NMR信息丰富和对样品无破坏性的优点在样品的初筛和组分判别得以更充分的体现。更多还原

【Abstract】 With 2D DOSY technique,the NMR application was invested in the component identification of mixture samples with- out separation.The result showed that the component in the mixture samples could be identified with chromatography-like 2D NMR spectrums using 2D DOSY technique.It was showed that taking the advantage of NMR properties,such as rich informa- tion and un-damage to the samples,DOSY technique could be used as an useful tool for providing original information for mixture samples.更多还原
