采用原子荧光分析技术,并基于一种新型金汞齐富集装置,设计和研制出一种通用型原子荧光测汞仪,仪器可用于对固、液、气等各种类型样品中Hg的含量进行微量(痕量)分析,整个仪器系统在计算机的控制及样品进样系统的配合下,可自动完成对样品类型的选择及预处理、富集方式选择、信号检出和结果处理等测量全过程,线性范围达5～6个数量级,相关系数>0.998,液体样品的检出限达到0.0004 ng/mL;固体样品的检出限低于0.003 ng。
Using atomic fluorescence spectrometry, and based on a new gold amalgam enrichment device, a universal atomic fluorescence mercury detector was designed and developed. The instrument can be used to determine the content of Hg in solid, liquid and gas samples (Trace) analysis, the entire instrument system in the computer control and sample injection system with the automatic completion of the sample type selection and pretreatment, enrichment mode selection, signal detection and results of measurement and other measures The linear range was 5-6 orders of magnitude with a correlation coefficient> 0.998. The detection limit of liquid sample was 0.0004 ng / mL. The detection limit of solid sample was less than 0.003 ng.
