Abstract

The role of the counter anion in positive-ion matrix-assisted laser desorption/ionization (MALDI) mass spectrometry of poly(methyl methacrylate) (PMMA) has been investigated. When PMMA was analyzed by MALDI in the presence of different alkali metal halides, A⁺X^-, ion yields decreased on changing X^- from I^- to Br^- to Cl^-. The effects of changing the alkali metal cation A⁺ were greater when X^- was chloride than when X^- was iodide. With a mixture of two different alkali metal cations, PMMA showed different affinities for the cations, dependent upon which counter anion was present.
