MONITORING DEVICE FOR MONITORING CHEMICAL REACTIONS USING MR MEASUREMENTS IN A FLOW-THROUGH CELL

摘要

A monitoring device for the analytical measurement of reaction fluid generated in a reaction vessel (1) in a spectrometer (2) with monitoring cell (3) and distributor device, into which at least four supply and return lines (4i ', 4o', 4i "4o"), the distributor device comprising a distributor device (5) for distributing reaction liquid onto the supply and return lines, characterized in that the distributor device has a distributor container (60) in which the distributor Device and an electrically controllable pumping means (61) are arranged for pumping reaction liquid, that the distributor device comprises an electrically controllable valve means (50) for distributing reaction liquid to the lines opening into the distribution container lines, and that a control and Regulating device (70) for the electrical control of the pump direction and for electrical control of the valve device is present. This enables a timely, automated reaction control, which can be specifically optimized with regard to selected process parameters, via which further control steps can be initiated. It provides a possibility of temperature control, which includes the entire flow path, the monitoring device is spatially very compact.
