氢气具有较强的映震灵敏性，氢气观测是探索地震短临预报的新途径。ATG-6118H痕量氢气在线自动分析仪是一种用于测量地下流体逸出氢气的新型数字化观测仪器，可以现场进行全自动连续测定，具有灵敏度高、自动化程度高、功耗低、操作简单等特点，具有网络远程诊断和数据处理分析功能，可以精确分析空气及井水中逸出的痕量氢背景值。目前我国尚未形成统一的痕量氢分析仪的检测规范，本文根据实际检测要求，对ATG-6118H痕量氢气在线自动分析仪进行了校准实验、检出限实验以及精确度实验，并对8台仪器性能进行了对比。通过指标评价确定了该仪器的性能检测方法的可行性，适合在具备数字化观测条件的全国地震地下流体台站以及具备断层气观测条件的台站推广应用。

The hydrogen has strong reflection sensitivity,and hydrogen observation is a new way to explore the forecast of earthquake. The on-line automatic trace hydrogen analyzer ATG-6118H is a new digital observation instrument used to measuring escaped hydrogen gas from the underground fluid,it can be fully automatic analysis of related samples on site,with the characteristic of high sensitivity,high degree of automation,low consumed,easy to operate,etc,and it has the function of network remote diagnosis and data processing analysis,and it can also accurately analyzes the trace hydrogen background value of air and well water. At present,there is no uniform testing standard of trace hydrogen analyzer in China,according to the actual testing requirements,calibration experiment,detection limit test,precision and accuracy experiments of the on-line automatic trace hydrogen analyzer ATG-6118H were carried out in this paper,and the performance of eight instruments was also compared. The feasibility of the instrument's performance detection method is determined by the index evaluation,so it is suitable for broad popularization and application of seismic subsurface fluid stationsas well as fault gas observation stations throughout the country with digital observation conditions.
