提出了一种以湿法蚀刻技术制备的用于流动注射 (FI)或顺序注射 (SI)进样可更新表面检测的芯片式流通池 ,并将此流通池与SI系统及检测器相匹配 ,用于顺序注射可更新表面 (SI RST)反射光谱法检测 .流通池由两片玻璃封接而成 ,流通池通道蚀刻在玻璃基片上 .流通池通过多股双岔光纤分别与光源、检测器相耦合 ,以实现对微珠表面的反射光谱法检测 .将此SI RST反射光谱法检测系统用于对锌的检测 ,并测定人发试样中微量锌的含量
A chip-type flow cell prepared by wet etching technique for flow injection (FI) or sequential injection (SI) injection was developed. The flow cell was matched with the SI system and the detector. (SI RST) Reflectance Spectroscopy Detecting Flow cells are sealed with two pieces of glass, and the flow cell channels are etched into the glass substrate.The flow cell is connected to the light source, the detector In order to achieve the detection of microbeads surface by reflection spectroscopy.The SI RST reflectance spectroscopy detection system for the detection of zinc and determination of human hair samples of trace zinc content
