A method for introducing a liquid sample into an NMR spectrometer to measure an NMR spectrum of the liquid sample, wherein the liquid sample is injected into a supply line and wherein further liquids are supplied into the supply line following the liquid sample, which are separated from each other and from the liquid sample by gas bubbles is characterized in that the liquid sample is supplied via an injection inlet to a valve configuration whose output side can be connected to the supply line and the further liquids and gas are supplied to the valve configuration via supply lines, wherein a desired sequence of sample segments, gas bubbles and further liquid segments is generated through temporally matched switching of the valve configuration in the supply line and is supplied to the NMR spectrometer. The inventive method realizes supply of a liquid sample into an NMR spectrometer with rapid sample transfer while thereby preventing mixing and dilution of the individual segments.
