Buffer exchange is often necessary when the buffer composition of the sample needs to be changed between chromatography steps. Desalting of a sample is often performed before ion exchange (IEX) and multimodal

Instructions WebJul 5, 2024 · Adding Base to the Buffer. When base is added it reacts with the H + ions in the buffer, and this (temporarily) reduces the concentration of the H + ion. This causes a disturbance to the equilibrium, and causes a response predicted by the Le Chatelier Principle – more of the acid molecules dissociate to increase the concentration of H + … fabgenics

WebTherefore, a buffer must consist of a mixture of a weak conjugate acid-base pair. The pH a buffer maintains is determined by the nature of the conjugate pair and the concentrations of both components. A mixture of acetic acid and sodium acetate is acidic because the K a of acetic acid is greater than the K b of its conjugate base acetate. It is ...
