ABSTRACT:
A method for coupling a gas chromatograph (21) to an NMR spectrometer, wherein the carrier gas present at the outlet of a separating column (23) of the gas chromatograph (21) including a sample contained in the carrier gas is supplied via a heated transfer line (1) to a collecting device (2) for the sample contained in the carrier gas, is characterized in that the carrier gas containing the sample is introduced into a collecting liquid (8) in the collecting device (2), and the sample is collected in the collecting liquid (8), wherein the collecting liquid (8) is suitable as an NMR solvent for the sample. The sample loss of the coupling method is reduced.
