Determination of trace amounts of nitrites by the quenching effect on the fluorescence emitted by acridine red 吖啶红荧光猝灭法测定痕量亚硝酸根
Fluorimetric determination of trace selenium in selemium salt with benzimidazole derivative by fluorescence quenching effect 苯并咪唑衍生物荧光猝灭法测定硒盐中的微量硒
It measures the density of oxygen by detecting the life - span of the fluorescence quenching . the so - called fluorescence quenching is a kind of physics or chemistry process that the fluorescence material has chemical or physical reactions with certain substance is selected here . it has the advantage of good stability of fluorescence , long life span and the strong quenching effect 本课题光纤氧气传感器检测系统是基于荧光猝灭效应的检测机制,通过测定荧光寿命从而检测氧气浓度的,荧光猝灭效应所引起的荧光寿命具有很好的稳定性、猝灭效果以及系统使用寿命长。
