NMR spectroscopy has long been recognized as a powerful quantitative analytical tool. Quantification is commonly done against internal and external standards. A third approach is to quantify against an electronic reference, which combines the advantages of the two methods. The implementation of this approach in solid-state NMR is more challenging due to the single-coil design of double resonance probes. In this study, a novel approach for implementing the electronic referencing method in solid-state NMR by injecting the reference signal using a broadband antenna installed near the NMR receiver coil is presented. This method demonstrates excellent accuracy and precision, as it remains robust to changes in the electronic conditions of the probe, including tuning and matching errors.

调谐和匹配误差补偿定量固态核磁共振

核磁共振波谱长期以来被认为是一种强大的定量分析工具。量化通常根据内部和外部标准进行。第三种方法是根据电子参考进行量化，它结合了两种方法的优点。由于双共振探针的单线圈设计，这种方法在固态核磁共振中的实施更具挑战性。在这项研究中，提出了一种通过使用安装在 NMR 接收器线圈附近的宽带天线注入参考信号来实现固态 NMR 中电子参考方法的新方法。该方法表现出出色的准确性和精密度，因为它对探头电子条件的变化（包括调谐和匹配误差）保持稳健。
