Webtrimethylamine (TEA) buffer (30 mL TEA + 940 mL H2O, pH 3 with H3PO4) (eluant A) and ACN (eluant B), respectively. Each sample was desorbed in 2 mL of desorption solution (60 mL TEA buffer + 140 mL ACN and 400 mL DMF). The LC method used an isocratic elution program, 25% A and 75% B, at 1 mL/min, 8 µL sample injection and column kept at 30°C.

WebIn case of the TEAA buffer, the favorable separation was maintained even at a low salt concentration, such as 10mM. The mobile phase consisting of TEAA and acetonitrile has been used commonly in RP-HPLC separation of oligonucleotides, but a high salt concentration is usually necessary to improve the poor retention Web• Triethylamine (TEA) This may suppress the ionisation of less basic compounds in positive ion mode (as TFA is readily ionised to give a [M+H]+ ion at m/z 102). In negative mode analysis, TEA enhances ionisation of other compounds as TEA is basic. This is a particularly useful additives for the analyses of nucleic acids. • Tetrahydrofuran (THF) WebSince unadjusted triethylammonium acetate salt solutions contain neither conjugate acid nor conjugate base, they are not buffers.
