| 摘 要： | 以核磁共振技术测定标准物质磺胺对甲氧嘧啶的含量为例，建立了磺胺类标准物质期间核查NMR定量分析方法. 结果得到磺胺对甲氧嘧啶在1.00~20.00 mg/mL浓度范围内具有良好线性关系，回归方程为：y=0.112 8x+0.016 2，R=0.999 0，测定结果的误差<0.7%. 结果表明，NMR定量分析方法简便、准确、稳定性好，可作为磺胺类标准物质期间核查溯源性定值分析方法.

| Abstract: | A quantitative NMR method for analyzing sulfonamides reference materials based on determination of Sulfameter content was developed. The liner range of the method was found to be 1.00~20.00 mg/mL. The regression equation derived was y=0.112 8x+0.016 2, R=0.999 0, and the relative deviation was less than 0.7%. The results of this study showed that quantitative NMR analysis provides a simple, convenient, accurate and stable method for period verification of sulfonamides reference materials. |
