Gas inlet line - and - circulation means includes for tracking of reactions in the liquid phase with the participation of gaseous reactants under normal - and high pressure by nuclear magnetic resonance spectroscopy (pressure - nmr - spectroscopy) under stationary conditions

摘要

Gas circulation system the direction of the tracking of reactions in the liquid phase with the participation of gaseous reactants under pressure, by means of magnetic resonance - spectroscopy (nmr) under stationary conditions with an nmr measuring cell for a sample solution with a gas inlet - and a gas line capillary, as well as a closure with passages for the gas inlet - and the gas line capillary, a gas reservoir for a reaction gas, with a pressure regulator for adjusting the required total pressure, with valves, and with the monitoring of pressure sensors serving, characterized in that a both the delivering reaction gas, as well as after flowing through the nmr - measuring cell pump and which receives an electrically controllable solenoid valves (11) in the rectifier circuit via a control unit for the electric control of the piston pump valves and solenoid valves (11) for the transport of the reaction gas are connected such that the reaction gas direction dependent on the gas inlet - (1) and the gas line capillary (2) is guided in a closed circuit, wherein in each case both the spool by the movement of the piston cylinder part volume of the piston pump with the gas line capillary (1) as well as the enlarging cylinder part volume of the piston pump..
