Laser Desorption Low-Temperature Plasma Mass Spectrometry Imaging (LD-LTP MSI) of tobacco seedlings

Mass spectrometry imaging (MSI) data set in imzML format, of complete tobacco (Nicotiana tabacum) seedling using Laser Desorption Low-Temperature Plasma ionization. Mapping the ion that corresponds to nicotine shows accumulation in the roots and at the borders of leaves.

The experiment is described in:
