constant ionic-strength buffers for enzyme kinetics

[Achim Recktenwald]

In 1982 in Methods in Enzymology, vol. 87, chapter 23, pp.405
K.J. Ellis and J.F. Morrison published a paper titled:
Buffers of constant ionic strength for studying pH-depedent processes.

It describes how to calculate and prepare buffers and mixtures of
buffers of constant ionic strength over a wide pH-range.

My question: Does anybody know of other similar publications ?

Thanks in advance,

Achim
