Mineral reference solution for test kits (Ca, Mg, KH, K+)
Reagents in test kits can lose their effectiveness and accuracy over time due to unfavourable storage conditions, high or low temperature and through exposure to oxygen. This can then lead to incorrect results. The respective tests should therefore be checked against a stable standard on a regular basis.
Tropic Marin Multi-Standard is a solution, produced in the laboratory, and tested by means of ICP-OES. The solution is made with measured concentrations of calcium, magnesium, potassium and KH/ alkalinity. It can be used to check the accuracy of test kits for those parameters and to calculate a correction factor, if the test kit is found to have a variance.
