摘　　要：氢化物发生—原子荧光光谱(HG-AFS)法测定化探样品中的汞时,常会出现仪器测定空白值过高或不稳定、标准工作曲线的线性差、样品测定结果的重现性差等问题。本文就所使用的AFS-2202E双道原子荧光分光光度计,简要介绍其在日常生产中的常见故障及排除方法,使汞的测定满足多目标地球化学样品中汞的测定要求。Some problems will be founded, such as high blank value and instability, poor linearity of standard working curve, poor reproducibility of measured results when using Hydride Atomic Fluorescence Spectrometry（ HG -AFS） to determine mercury in geochemical samples. The common problems and removing methods in production is studied, to meet the challenge of determination of concentrations of mercury in multipurpose geochemical samples.
