Application

Ammonium acetate can be used as a:
  • Mobile phase in the derivatization reaction to enhance the detection and separation of glyphosate and aminomethylphosphonic acid (AMPA) using reversed-phase liquid chromatography (RPLC).
  • Buffer component in the mobile phase of the Hydrophilic Interaction Liquid Chromatography (HILIC) method for the separation and determination of polar lipid classes.

General description

Ammonium acetate is commonly used as a buffer in high-performance liquid chromatography (HPLC). It is used as a mobile phase to develop a novel speciation methodology applicable to urine samples using IEC-ICP-MS.
