The process described will yield a final concentration less than 10mM
NaPO4. Make a 10x (100mM) solution of NaPO4, use an aliquot of this
to make a preliminary solution of about 75% the desired final volume,
adjust to the desired pH with a concentrated (1 M perhaps) solution
of citric acid, then add water to the final volume. Re-check pH and
adjust after the solution has stood a while ( dilution and temperature
shifts may affect the final pH). Calbiochem used to distribute a great
little pamphlet on buffer preparation and theory. Hope this helps.
