Mineral reference solution for test kits (NO3, PO4)
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 NP Standard consists of a solution with nitrate and phosphate, in known concentrations, prepared in the test laboratory. It allows you to quickly check the precision of test kits for nitrate and phosphate. The deviation can be determined and a correction factor can be calculated as necessary.
