摘要
对超导脉冲傅里叶变换核磁共振谱仪校准规范JJF 1448–2014进行了解读.通过对超导脉冲傅里叶变换核磁共振谱仪主要技术指标的类型分析,说明了采用乙基苯溶液标准物质、氯仿溶液标准物质、氘代苯/p-二氧六环溶液标准物质被采用的原因及其在JJF 1448–2014校准方法中的特点及优势.新规范校准方法合理、所采用的标准物质结构简单、能够对仪器的主要技术指标进行校准,提高了效率,满足大部分傅里叶变换核磁共振的校准要求.
Abstract
Calibration Specification for Superconducting Pulsed Fourier Transform Nuclear Magnetic Resonance Spectrometers JJF1448–2014 was conducted. Through the analysis of the main technical indicators of the superconducting pulsed Fourier transform nuclear magnetic resonance spectrometers, the reasons of ethyl benzene certified reference material,chloroform certified reference material,deuterated benzene/p-dioxane certified reference material and the features and advantages of calibration method in calibration specification JJF 1448–2014 were expounded. New standard calibration method is reasonable, the standards materials have simple structure, and can calibrate the main technical index of instruments, the efficiency was improved, it meets the most of the Fourier transform nuclear magnetic resonance (NMR) calibration requirements.
