Spectra Online

Finally, use of the loop-storage/loop-transfer technique provides an escape from this dilemma. The chromatogram is acquired without any interruption, the mass spectrometer acquires MS and MS2 spectra online, and provides spectroscopic information which allows reliable peak selection for the storage procedure. The MS unit is used above all as a very selective and sensitive detector. After the chromatographic separation, it is available for other purposes and the collected samples are then independently analysed in the NMR spectrometer.
