目的:建立脂肪乳注射液中铝含量的测定方法,探讨其合理的限度范围。方法:采用电感耦合等离子体-质谱法(ICP-MS法)对15家企业生产的69批脂肪乳注射液的铝含量进行测定,针对脂肪乳注射液在ICP-MS法测定中内标元素的选择、定量方法、介质、样品前处理方法以及方法学的建立进行研究。结果:所测得的铝浓度在0.5ng∙mL^(-1)~5.0 ng∙mL^(-1)内线性关系良好,相关系数(r)为0.9999,平均回收率为101.1%,RSD为1.83%(n=9)。结论:ICP-MS法适用于脂肪乳注射液中铝含量的测定。国内该类制剂的铝含量不同生产企业间存在较大差异,有必要控制大容量肠外营养制剂中脂肪乳注射液铝的残留量。

火电厂烟道属于大截面烟道,由于锅炉结构的限制,烟道流场分布不均匀。尤其是脱硝出口烟道,普遍存在着催化还原反应不均匀、烟道直管段短的问题,烟气浓度场分布不均匀。在流场不均的烟道,单点取样测量的烟气数据不能代表烟气的实际参数,... 详细信息

火电厂烟道属于大截面烟道,由于锅炉结构的限制,烟道流场分布不均匀。尤其是脱硝出口烟道,普遍存在着催化还原反应不均匀、烟道直管段短的问题,烟气浓度场分布不均匀。在流场不均的烟道,单点取样测量的烟气数据不能代表烟气的实际参数,不能作为生产运行调节的参考依据。本文通过对比几种应用于烟气取样的典型取样技术,提出了适用于不均匀流场烟道的矩阵取样技术,为火电厂烟气取样分析提供指导。
