Research output: Patent

Abstract

A method for preparing a composition that includes selecting a pH of the composition; selecting a first buffer with a negative temperature coefficient; selecting a second buffer with a positive temperature coefficient; and forming the composition comprising the first buffer and the second buffer. The composition has an average temperature coefficient, ΔpH/ΔT(Ta,Tb)≦1×10−3 pH-unit/K and a ΔpH(Ta,Tb)≦0.31 pH-unit for Ta=4 K and Tb=313 K.
