Certificates of Analysis

Magnesium is present in water samples as a dissolved salt from magnesium carbonate. The concentration of magnesium, along with calcium, represent the total hardness of the water sample. High levels of water hardness contribute to pipe rusting in boilers and cooling systems as well as demineralisation and reverse osmosis plants, so it is important to monitor and minimise magnesium levels.


Hanna can provide a range of portable and bench Photometers for accurate determination of magnesium levels.
