摘要
本文分析了NMR外标参比积分法中影响测定精度的各种因素,通过实例说明了饱和效应、偏置效应和旋转边带对测定精度的影响程度,并指出了消除各种误差的有效方法。
A quantitative NMR method by using an external reference has been developed. Various factors which affect its precision, such as saturation effect, offset effect and the effect of rotation sidebands,are discussed in detail.The method is suitable for determining common inorganic ions.
