HI-93752-03 Calcium and Magnesium HR, Oxalate (Ca) and Calmagite (Mg) information

Hanna's extended description

The HI-93752-03 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow an adaptation of the calmagite method for determining calcium, and the oxalate method for magnesium. By simply adding the HI-93752-01 reagents to the sample, the reaction will take place and one of Hanna’s compatible benchtop or portable meters will determine the concentration from the colour that is produced. The results will be displayed in mg/L (ppm) as calcium or magnesium, depending on the method used. These reagents are designed to be used with samples that have an expected range of 0 to 400 mg/L calcium hardness, and 0 to 150 mg/L magnesium hardness.

  • Tip for an accurate measurement

    It is important that the sample does not contain any debris.

    When the cuvette is placed into the measurement cell, it must be dry outside and completely free of fingerprints, oil or dirt. Wipe it thoroughly with HI-731318 or a lint-free cloth prior to insertion.

    Shaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette.

    Do not let the reacted sample stand for too long after reagent is added, or accuracy will be lost.

    After the reading, it is important to discard the sample immediately, otherwise the glass might become permanently stained.
