Hanna's extended description

Reagent for HI -729 Fluoride Low Range Pocket Checker



The HI-729-26 are high-quality reagents that are pre-measured, allowing for users to achieve fast and accurate measurements with their Fluoride Low Range Checker® HC. These reagents follow the SPADNS Method in which the reaction between fluoride and the reagent causes a colourless complex in the sample. By simply adding 2 mL of SPADNS reagent to two cuvettes, and subsequently 8 mL of deionised water to one and 8 mL of sample in the other, the reaction will take place and the HI-729 will determine the concentration from the colour that is produced. The results will be displayed in ppm of fluoride. These reagents are designed to be used with samples that have an expected range of 0.00 to 2.00 ppm (mg/L) fluoride.

Tip for an accurate measurement

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

Whenever 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.
