摘要
以磺胺对甲氧嘧啶为例,对有机标准物质期间核查核磁共振定量分析方法的仪器参数作了研究,主要包括脉冲宽度、弛豫延迟时间、扫描次数、谱宽、发射机频率偏移、时域数据长度。分别对磺胺、磺胺对甲氧嘧啶、磺胺间甲氧嘧啶、磺胺噻唑、磺胺嘧啶、磺胺吡啶、磺胺苯吡唑7种磺胺类标准物质进行期间核查含量测定,测定结果的相对误差为0.1%～0.3%,准确度与高压液相色谱方法相当。
Sulfameter as a sample, the instrument parameters of NMR including pulse width, delay time, number of scans, spectral width etc. for quantitative analysis to the organic standard substances period verification were discussed. The relative error of sulfanilamide, sulfameter, sulfamonomethoxine, sulfathiazloe, sulfadiazine, sulfapyridine and sulfaphenazolum reference materials determined by NMR were 0.1%-0.3%, which matched HPLC method in accuracy.
