为了实现快速、无损、实时检测和分析臭灵丹中微量元素的含量,现对高精度臭灵丹微量元素检测系统进行设计;使用当前方法检测臭灵丹时,无法在保证微量元素活性的条件下提取微量元素;为此,提出一种基于Taguchi的高精度臭灵丹微量元素含量检测系统设计方法;该方法使用日本理学ZSX100型X射线荧光光谱仪采集臭灵丹微量元素光谱,确定微量元素种类,利用超临界萃取技术中的两大技术超临界流体萃取技术和超临界固体萃取技术萃取出臭灵丹中的微量元素,再经过超滤分离法中直线段、曲线段、水平段3个阶段分离出萃取液中微量元素,以ICP-MS法计算出微量元素的含量,达到对臭灵丹中微量元素含量的高精度检测;实验仿真证明,所提方法可以快速、无损、实时检测和分析臭灵丹中微量元素.%In order to achieve a rapid,nondestructive,real-time detection and analysis of the content of trace elements in Herba Laggerae,need to study the system of detection of trace elements in high precision.The current method is used to detect pterodontic,unable to ensure extraction of trace elements activity conditions.The method of using RIGAKU ZSX100 X-ray fluorescence spectrometer X acquisition pterodontic trace element spectrum to determine trace element types,two technology using ultra supercritical extraction technology of supercritical fluid extraction and supercritical extraction technology to extract solid trace elements from Laggera pterodonta,after ultrafiltration separation in straight line and curve section and horizontal section three stages separation of trace elements in the extract,using ICP-MS method to calculate the content of trace elements,to achieve high precision detection of the content of trace elements in Herba laggerae.Simulation results show that the proposed method can fast,nondestructive,real-time detection and analysis of trace elements in Herba Laggerae.
