Sequential injection analysis in capillary format with an electroosmotic pump.
A system of sequential injection analysis (SIA) in capillary format based on an electroosmotic pump is introduced. The system exhibits excellent reliability and reproducibility (relative standard deviation 0.6-0.8%) for both simple and complex chemical reaction systems. The simplicity and flexibility of the field-decoupled electroosmotic pump has been found to be ideally suited for SIA. There is significant potential for miniaturizing the necessary instrumentation.
