光电导检测器是一种两用的检测器,它既可以做为通用的电导检测器,通过待测组分电导的改变而用于离子组分的检测;也可以做为一种选择性的检测器——光电导检测器,测定在一般情况下不电离,但经过光化学作用后才电离的组分。由于使用柱后光化学反应,并和电导定量检测结合起来,从而提高了该检测器的灵敏度和选择性。由于溶剂系统中使用了离子交换管
Photoconductivity detector is a dual-purpose detector, which can be used as a general-purpose conductivity detector for the detection of ionic components through the change of conductance of the components to be measured. It can also be used as a selective Detector - A photoconductive detector that measures the components that are not ionized under normal conditions but ionize only after photochemical effect. The post-column photochemical reaction is combined with conductivity quantification to enhance the detector’s sensitivity and selectivity. Due to the use of ion exchange tubes in solvent systems
