Description

Application

Biological buffer component with sodium hydroxide and sodium chloride (pH 5.67-7.57, useful pH range 6.4-7.4). Used to prepare immobilized pH gradients.

ADA, or N-(2-Acetamido)iminodiacetic acid, can be used to study biological buffers and zwitterionic compounds. ADA has been used in a study to describe the application of scanning capacitively coupled contactless conductivity detection (SC(4)D) for the determination of pH dependant behaviour of two aminopolycarboxylates immobilised onto the surface of a monolithic capillary column.
