Web2 apr. 2013 · The great power of ion-exchange chromatography to bring about complex separations was aptly demonstrated by Moore and Stein (1); this work eventually led to their receiving the 1972 Nobel laurel. They were able to separate all 50 amino acids in 175 h (slightly more than a week) using a 100 cm × 0.9 cm column packed with 25–37 µm … Web24 mrt. 2024 · Generally speaking, the effective pH range of buffer is about pKa ± 2ph unit, and to obtain strong enough buffer capacity, the pH is preferably between pKa ± 0.5ph unit. When the ratio of weak acid (or weak base) to the amount of corresponding salt is close to 1:1, the buffer capacity of this buffer system is the strongest.
