A simple device for the extraction of TLC spots: direct coupling with an electrospray mass spectrometer.
A new device is described which allows the recovery of compounds from thin layer chromatograms in short times, within a small volume, and without contamination. This apparatus can be coupled online to an electrospray mass spectrometer, but can also be used with other detectors or for micropreparations.
