West Coast HILIC ... 2017 11:41 pm Hi all, Quick question for anyone who has experience working with high pH mobile phases. Dissolution of ammonium acetate salt in water results in pH 7, but this pH is highly labile. H. 2. Acetate and formate buffer in the acidic range, not in the alkaline range. pKa 25°C . Ammonium bicarbonate was proposed as an alternative volatile buffer for native protein analysis due to its high buffering capacity at near neutral pH [42–46]. Its accurate composition, high pH factor and longer shelf life make it more demanding. As we need couple our IMER(immobilezed enzyme reactor) in this system, and need a pH range of 7.4, so this kind of ammunium bicarbonate buffer is the only one suit for our HPLC-MS system.
