薄层电化学传感器有高灵敏(ng)、用样少(1～50μl)、装置简单、结合流动注射分析(FIA)有高分析速度(每小时200次)、柱液相色谱(HPLC)有快速分离复杂混合试样、离子选择性电极有选择性好等优点。所以引起广泛重视,发展迅速,每年约有近百篇文章发表。新近介绍的直接和间接示差电位法、光辐射电检测法、电化学发光分析法等、流动薄层电化学传感器已兼有HPLC的荧光、紫外、折射等检测器的分析能力。
Thin-layer electrochemical sensors are characterized by high sensitivity (ng), low sample count (1 ~ 50μl), simple device, high speed of analysis combined with FIA (200 times per hour), column liquid chromatography Rapid separation of complex mixed samples, ion selective electrode has good selectivity and so on. Therefore, it has drawn wide attention and developed rapidly. There are about one hundred articles published each year. Newly introduced direct and indirect differential potentiometry, optical radiation detection, electrochemical luminescence analysis, flow thin-layer electrochemical sensors have both HPLC fluorescence, UV, refraction and other detector analysis.
