Addition of ammonium acetate to the mobile phase in direct-liquid-introduction mass spectrometry enhances the abundance of the protonated molecular ion or ammonium*molecular ion complex for compounds of biological interest.The efficacy of the method was investigated by comparing mass spectra obtained, with and without ammonium acetate, for a variety of underivatized, per-O-acetylated, and per-O-alkylated carbohydrates, and for several underivatized peptides.The mass spectra of the per-O-alkylated carbohydrates obtained by direct-liquid-introduction mass spectrometry with ammonium acetate were also compared to those obtained by thermospray mass spectrometry.
