Triethylammonium acetate

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 conjugate acid nor conjugate base, they are not buffers.
