Abstract
Development of a micro device for NMR and its application for in-site monitoring of chemical synthesis were described. Since this device can be inserted into a 5 mm φ NMR sample tube, it is possible to carry out an in-site monitoring of chemical synthesis using a microchip combined with a standard NMR instrument. The performance was demonstrated the direct detection of the intermediates of Grignard reaction. © 2006 Society for Chemistry and Micro-Nano Systems.
