General description

This certified eluent concentrate for ion chromatography is traceable by potentiometric titration to NIST Standard Reference Material. It is certified in accordance with ISO Guide 31. All details about exact content, uncertainty, traceability and expiry date are described in the certificate.

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.
