Buffers and Eluent Additives for HPLC Method Development

Ammonium hydrogen carbonate is an excellent buffer for use at high-pH with good buffering capacity over pH 8-11 and possibly wider at higher ionic strength. The extended buffering range is due to the ammonia – ammonium buffering capacity being additive to the hydrogen carbonate-carbonate capacity in what is traditionally called a ‘mixed

ammonium bicarbonate Vs ammonia buffer - Chromatography …

Jan 07, 2008· Ammonium carbonate is a very nice buffer from pH 9-10 because you are at the pKa of both the ammonium and the carbonate. To get the same buffering capacity out of ammonia by itself, I guess you''d need at least twice the molarity. To make the baseline a little better, maybe you could try adding ammonium bicarbonate to the acetonitrile as well.
