Purge the pumping system of any buffer-containing mobile phases and connect the inlet end of the column to the injector outlet. Since a buffer is intended to give only a small change in pH with added H + or OH −, the best buffer for a given pH is the one that gives the smallest change.As may be seen from the Henderson–Hasselbalch equation, when the pH of the solution equals the pK′ of the buffer, [conjugate base] = [acid], and the buffer can therefore respond equally to both added acid and added base. 4 This new edition features updates throughout with coverage of all aspects of influenza, systematically covering biology, virology, diagnostics, ecology, epidemiology, clinical medicine, and the control.
