摘要
挥发性有机物(VOCs)在线分析仪通过在线集成的方式接入水质自动监测站,采用动态吹脱捕集气相色谱法快速分析。具有线性好、检出限低、精密度高、准确度好等特点。并在上下游的比对监测中具有良好的可比性、一致性和连续性。初步探索了VOCs预警监测的方法,并对预警阈值的设定进行了探讨。
in this application,the volatile organic compounds（ VOCs） online analyzer,which used the dynamic purge and trap gas chromatography analysis,was integrated into the automatic monitoring station. The monitored results showed good linearity,low detecting limit,high precision,and good accuracy,and in the comparison for the upstream and downstream monitoring,a good comparability,consistency and continuity was observed. In this paper,we also explored the methods of early- warning monitoring for VOCs,and discussed the setting of early- warning threshold.
