Microchip is a glass plate that has a microchannel typically below 100 m. Various chemical process can be performed in flow by introducing sample solution through this microchannel. One of the application of microchip is solvent extraction. If microchip can be applied to Pu analysis, it is possible to reduce waste generation, radiation exposure of laboratory staff and simplify the analytical operation. In this study, we have developed an online alpha liquid scintillation measurement system coupled with microchip application to the separation field of analysis pretreatment. Quantitative analysis of plutonium has been performed by using the developed system. In the conference, we present these experimental results.
