Benchtop NMR Signal Enhancement of Metabolites in Urine Extract using SABRE -...

Metabolites in a urine extract are signal-enhanced by SABRE hyperpolarization and detected using a benchtop NMR spectrometer. Quantification by standard addition is demonstrated...尿液提取物中的代谢物经SABRE超极化（SABRE hyperpolarization）实现信号增强，并通过台式核磁共振波谱仪完成检测；本研究验证了采用标准加入法进行定量分析的可行性……
