Abstract:
1. A nuclear magnetic resonance measurement apparatus comprising: a reservoir for holding a mixture solution containing a first compound and a second compound of lower molecular weight than that of the first compound; a magnet for applying a magnetic field to said mixture solution held in said reservoir; a nuclear magnetic resonance probe attached to said reservoir; a mixing filter for mixing a first solution containing said first compound and a second solution containing said second compound and draining a resultant solution as said mixture solution; a separation filter for performing separation between said first solution and said second solution from said mixture solution injected thereto; and pipes for constituting a first flow channel through which said first solution drained out of said separation filter is injected to said mixing filter, a second flow channel through which said second solution drained out of said separation filter is injected to said mixing filter and a third flow channel through which said mixture solution drained out of said mixing filter is injected to said separation filter by way of said reservoir.
