本文报导用玻璃碳材料试制成功的薄层流动式电化学检测器。这是一种新型的快速、简单、高灵敏度液相色谱检测器。用铁氰化钾作性能鉴定,取样范围1—20微升,测定1.0—5.0微克的Fe(Ⅲ)时,精密度±6％,回收率97—102％。灵敏度可到0.1微克,电解响应快,1分钟完成测试。 This article reports a successful thin-layer flow electrochemical detector made of glassy carbon material. This is a new type of fast, simple, high sensitivity liquid chromatography detector. Potassium ferricyanide for performance identification, the sampling range of 1-20 microliters, the determination of 1.0-5.0 micrograms of Fe (Ⅲ), the precision of ± 6%, the recovery rate of 97-102%. Sensitivity to 0.1 micrograms, electrolytic response fast, 1 minute to complete the test.
