Description

General description

The “bicarbonate concentrate” is basically 0.1-molar solution of sodium bicarbonate (the saturation temperature of the 0.1-molar solution is 15°C). It is highly advantageous as it is temperature dependent and its subsequent dilution with water can be appropriately controlled.

This eluent concentrate for ion chromatography is determined by potentiometric titration. Content and expiry date can be found on the certificate.
