Abstract:
... The performance of the most common and also some other less common CE buffers has been tested for the pKa determination of several types of compounds (pyridine, amines, and phenols). The selected buffers cover a pH ranging from 3.7 to 11.8. Whereas some buffers, like acetic acid/acetate, BisTrisH⁺/BisTris, TrisH⁺/Tris, CHES/CHES⁻, and CAPS/CAPS⁻ can be used with all type of analytes, others like a ...
