LMJ-SSP

Video of the Auto Surface Sampling Probe in use.
Making contact with the surface through automated control.

Video of the HandsFree TLC/MS (c) software in use.
The probing tip scanned over a stamped text ("COPY") on paper and the image was reconstructed from MRM mass spectrometric signal of ink Rhodamine B used in the stamp.
