In LCMS and ion chromatography dibutylammonium acetate is primarily used as a mobile phase additive or ion-pairing reagent. It helps improve the separation and retention of polar and ionic compounds enhances peak shape and increases detection sensitivity. It is particularly useful for analyzing acidic or negatively charged analytes and ensures better chromatographic performance while remaining compatible with mass spectrometry detection.

for LC-MS & IC

Dibutylammonium acetate (0.5 M in HO) is an aqueous solution of a quaternary ammonium salt formed from dibutylamine and acetic acid. It appears as a clear colorless liquid and acts as a buffering agent with moderate ionic strength. Due to its volatility and compatibility with analytical instruments it is commonly used in techniques like LCMS (liquid chromatographymass spectrometry) and IC (ion chromatography).
