Triethylammonium acetate is a volatile salt, which is often used as an ion-pairing reagent in high-performance liquid chromatography separations of oligonucleotides. ^{[1] [2] [3] [4]} Since unadjusted triethylammonium acetate salt solutions contain neither a conjugate acid nor a conjugate base, they are not buffers.
