Influence of potassium chloride on the MALDI detection process

Usnic acid and its versatility as MALDI matrix

“…Contrary to reports on classic matrices like sinapic acid, 4 or 5 , 1a could not ionize larger proteins such as pork insulin, cytochrome C or horse myoglobin, even when extensive ionization energy was used. Consequently large peptides and proteins may require pre‐digestion before being analyzed by 1a .…”

Structural transformations in graphite induced by magneto-mechanical-milling in hydrogen atmosphere

“…The LTOF MS, described in detail elsewhere [12][13][14][15][16][17][18], was used for the mass characterization of the graphite powder milled in hydrogen atmosphere as well as for the starting graphite, which was a reference sample. The graphite sample placed on the holder was lighted by the focused pulsed laser beam (Fig.…”
