Addressing a Common Misconception: Ammonium Acetate as Neutral pH "Buffer" for Native Electrospray Mass Spectrometry - PubMed

Ammonium acetate nonetheless remains a useful additive for native ESI-MS. It is a volatile electrolyte that can mimic the solvation properties experienced by proteins under physiological conditions. Also, a drop from pH 7 to around pH 4.75 is less dramatic than the acidifiion that would take place in pure water.

Liquid Chromatography Mass Spectrometry (LCMS) - an …

8.4 Liquid chromatography–mass spectrometry (LC-MS) LC-MS is a chemistry technique that coines the physical separation capabilities of liquid chromatography (or HPLC) with the mass analysis capabilities of MS. LC-MS is a powerful technique used for many appliions, which has very high sensitivity and selectivity.
