Earlier work using field desorption mass spectrometry for the characterisation of guanidino containing bleomycins is extended to include bleomycin A2 and related substances. The new technique of fast atom bombardment mass spectrometry is assessed and compared with field desorption for the analysis of these complex antibiotics. Bleomycin A2 is shown to be more reactive to acetic anhydride than bleomycin B2. A procedure for in situ derivatisation for fast atom bombardment studies is described and unexpected catalysis in the glycerol matrix is reported.
