Several selected lichen samples are analysed by Fourier transform laser microprobe mass spectrometry with 5 μm resolution and with virtually no sample preparation. The application area can be increased to molecules with molecular weight higher than 500, because of the detection of post‐laser generated ions. In most cases, enough information is available to allow, in combination with IR and NMR data, complete structural characterization of the pigments, without the analysis of reference products.
