目的:建立复方龙血竭胶囊中铅、镉、砷、汞、铜5种重金属及有害元素含量的测定方法。方法:采用电感耦合等离子体质谱法(ICP-MS),样品经微波消解后测定,在线引入内标以校正基体效应。结果:各元素在一定浓度范围内线性关系良好(r≥0.9990);检测限为0.389 ng·g-1~3.548ng·g-1;加样回收率为87.5%~109.4%,RSD (n=9)均小于9.1%。结论:该方法较简便、快速、准确,可用于复方龙血竭胶囊中有害元素的测定。
目的:建立複方龍血竭膠囊中鉛、鎘、砷、汞、銅5種重金屬及有害元素含量的測定方法。方法:採用電感耦閤等離子體質譜法(ICP-MS),樣品經微波消解後測定,在線引入內標以校正基體效應。結果:各元素在一定濃度範圍內線性關繫良好(r≥0.9990);檢測限為0.389 ng·g-1~3.548ng·g-1;加樣迴收率為87.5%~109.4%,RSD (n=9)均小于9.1%。結論:該方法較簡便、快速、準確,可用于複方龍血竭膠囊中有害元素的測定。
