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:
- 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.
- 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.
- put tube on the left side of the color comparator box
- fill the vial to the 25 mg mark with sample
- add TPTZ powder reagent for iron. Swirl to mix
- wait for 3 minutes until a blue color appears
- fill a second tube to the top line with the prepared sample
- place the test tube in the color comparator box
- 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.
- 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.
