摘要
自制硝苯胺(钠)盐标准品,通过高分辨液相色谱-质谱联用法、核磁共振法和红外光谱法对其进行定性分析,采用高效液相色谱的质量平衡法对其纯度进行定值检测,并以差示扫描量热法辅助测定其纯度.分析结果表明,硝苯胺(钠)盐标准纯度为99.60%,该标准物质能够用于硝苯胺(钠)盐产品的准确定量.
Herein,a self-prepared nitroaniline(sodium)salt standard was qualitatively confirmed via high resolution liquid chromatography-mass spectrometry,nuclear magnetic resonance and infrared spectroscopy.Its purity was determined by high performance liquid chromatography-based mass balance method and differential scanning calorimetry.The result shows that the purity of nitroaniline(sodium)salt standard is 99.60%,indicating the promising application for accurate quantification of nitroaniline(sodium)salt product.
