Description

Description

The test kit can easily determine iron levels in the range 0 - 0,2 mg/L and 0 - 1,2 mg/L. The number of reagents is designed for 100 tests.

How to determine the amount of iron using the Hach test kit IR-21:

  1. install the adapter in the color comparator box (only if you are testing iron in the range 0 - 0.2 mg/L). The adapter shows the color in the tubes from top to bottom. Make sure the light source is above the tubes during color matching.
  2. test in the range of 0 - 0.2 mg/L fill the tube with sample to the upper line, test in the range of 0 - 1.2 mg/L fill the gauge with sample up to the 5 ml.
  3. put tube on the left side of the color comparator box
  4. fill the vial to the 25 mg mark with sample
  5. add TPTZ powder reagent for iron. Swirl to mix
  6. wait for 3 minutes until a blue color appears
  7. fill a second tube to the top line with the prepared sample
  8. place the test tube in the color comparator box
  9. hold the comparator box in front of the light. Rotate the color discs (use a color wheel according to the range of the test procedure) until the color match.
  10. chech the result in mg/L on the scale. If the sample is clear with no colors or turbidity, prepare a reagent blank for best results.
      • To prepare the reagent blank: fill the vial up to 25 ml mark with deionized water. Add one TPTZ reagent powder and swirl to mix. Transfuse the sample into a clean tube up to the upper line as described in step two and continue from step three.

    All necessary reagents and equipment are included in a portable case for analysis in the field.
