That's probably a salt which can be removed by lyophilisation together
with the solvent, e.g ammonium bicarbonate or triethylammonium
bicarbonate. They are used during purification by ion exchange
chromatography or ion pairing chromatography, especially for small
molecules where dialysis can not be used to remove excess salt.
