Ammonium acetate is an ammonium salt obtained by reaction of ammonia with acetic acid. A deliquescent white crystalline solid, it has a relatively low melting point (114degreeC) for a salt. Used as a food acidity regulator, although no longer approved for this purpose in the EU. It has a role as a food acidity regulator and a buffer.

work, phosphate, cannot be used. Ammonium acetate is sufficiently volatile for LC-MS use, but we are left with the 2.0<pH<3.8 and 5.8<pH<8.0 range to cover. Table 2 lists several additional buffers that are sufficiently volatile for LC-MS use. Ammonium formate (2.7<pH<3.7) does a fairly good job of filling buffer pH range LC-MS compatible
