description Since introduction of sinapinic acid (SA) and α-cyano-4-hydroxycinnamic acid as matrices, successful application of matrix-assisted laser desorption/ionization mass spectrometry started for protein/polypeptides. Both show some limitations in short peptide analysis because matrix clusters are quite abundant. Cinnamics currently used are E-cinnamics. Here, Z-SA as matrix for peptides is studied and compared with E-SA and α-cyano-4-hydroxycinnamic acid. Minor number of clusters is always observed in the low m/z region allowing the detection of short peptides.
