General description
Dibutylammonium acetate is an ion-pairing agent with quaternary ammonium ions. It generally helps in ionization of carbohydrate fragments providing a volatile solvent for the mass spectrometric technique.
Application
It has been used as buffer in mobile phase for separation and quantifying intracellular nucleotides from different microorganisms using ion pair reversed phase liquid chromatography electrospray ionization isotope dilution tandem mass spectrometry (IP–LC–ESI–ID–MS/MS) method.[1]
Packaging
Clear borosilicate glass, high hydrolytic resistance (Type I)
concentrate in ampules for 6x1 l 0.005 M ready-to-use solution
Legal Information
LiChropur is a trademark of Merck KGaA, Darmstadt, Germany
