Buffer for use in ion-exchange chromatography and electrophoresis.

• Density: 1,02 g/ml at 25 °C (lit.)
• pH: 8,5±0,1

Triethylammonium bicarbonate (TEAB) is a buffer, composed of a combination of triethylamine and carbon dioxide, the latter occuring in solution as bicarbonate. The volatility of TEAB facilitates sample recovery after chromatographic analysis and makes TEAB a buffer of interest for mass spectrometric analysis of biomolecules.

Synonyms: TEAB, triethylammonium hydrogen, carbonate buffer.
