Alpha-cyano-4-hydroxycinnamic acid (alpha-CHCA) as a matrix facilitates the ionization of proteins and peptides in a matrix-assisted laser desorption/ionization (MALDI) time-of-flight (TOF) mass spectrometer. The matrix itself also ionizes and so do its sodium and potassium adducts. Matrix clusters and metal
