    • Lasers with wavelengths at 2.79, 2.94, and 10.6 μm were used. Various small organic acids such as succinic, fumaric, lactic, nicotinic, and dihydroxybenzoic acids, urea, thiourea, and triethanolamine were tested as matrices.

    • The mass of these fragments was calculated from the known sequence of the digested plasmid DNA. The average mass of the two complementary strands was taken. Small deviations, caused by base modifications, cannot be excluded but should be well within the resolution of the detected signals.
