TM Calcium/Magnesium Combitest Professional

For high-precision determination of the calcium and magnesium concentration Calcium (Ca2+) and magnesium (Mg2+) are among the main components of natural seawater along with sodium, potassium, chloride and sulphate. For calcifying organisms, such as hard corals and red algae, magnesium and above all calcium are important growth factors - both elements form the basic substance of the calcareous skeleton. In addition, numerous biochemical processes involving magnesium and calcium take place In natural sea water, the calcium content is 400-410 mg/l and the magnesium content is 1280-1320 mg/l, and in a fixed ratio of 1:3.25 to each other. With the high-resolution titration test Tropic Marin®Calcium/Magnesium-Combitest Professional the concentration of both elements can be determined reliably and separately from each other with an accuracy of 4 mg/l Ca or 20 mg/l Mg.
