摘要
检出限作为一项重要的计量指标,广泛用于光谱、色谱、质谱等原理的水质分析仪器的评价,但是在电化学类仪器中却没有,这是由于这类仪器检测达到平衡时间长,难以得到稳定的低浓度溶液,最主要是因为电化学分析仪器为常规仪器,具有一定适用范围,不适用于微量物质的检测,因此常规方法得到的检出限在该范围之外,显得没有参考意义。
Detection limit,as an important measurement index,is widely used in the evaluation of water quality analysis instruments based on the principles of spectroscopy,chromatography and mass spectrometry,but it is not found in electrochemical instruments. This is due to the long equilibrium time of such instruments and the difficulty of obtaining stable low concentration solutions. The main reason is that electrochemical analysis instruments are conventional instruments and have certain application scope. It is not suitable for the detection of trace substances,so the detection limit obtained by conventional methods is beyond this range,which seems to be of no reference significance.
