Macherey-nagel Iron 1 Performing Colorimetric Tests Kit Instructions

MACHEREY-NAGEL Iron 1 Performing Colorimetric Tests Kit

Test kit for performing colorimetric tests on iron ions in surface water and sewage

Method

Colorimetric determination of Fe(II) and Fe(III) ions with a triazine derivate

Measurement range

0.04–1.0 mg/L Fe

Contents of test kit (refill pack)

sufficient for 200 tests

• 30 mL Fe-1*
• 2 screw-plug measuring glasses
• 1 slide comparator
• 1 color chart
• 1 plastic syringe 5 mL
• 1 instruction for use

Hazard warning:
Information regarding safety can be found on the box label and in the safety data sheet. You can download the SDS from www.mn-net.com/SDS.

Instructions for use

Also, refer to the pictogram on the back of the color chart

1. Pour a 5 mL water sample into each of the measuring glasses using the plastic syringe. Place a measuring glass on position A in the comparator.
   Only add the reagent to measuring glass B.
2. Add 5 drops of Fe-1, seal the glass, and mix.
3. Open the glass after 3 min and place it on position B in the comparator.
4. Slide the comparator until the colors match in the inspection hole on top. Check the measurement reading in the recess on the comparator reed. Mid-values can be estimated.
5. After use, rinse out both measuring glasses thoroughly and seal them.

The reagents can also be used for the photometric evaluation with photometers PF-12 and PF-12Plus.

This technique can be used also for analyzing seawater.

Disposing of the samples:
Information regarding disposal can be found in the safety data sheet. You can download the SDS from www.mn-net.com/SDS.

Interferences

The following quantities of ions will not interfere: ≤ 5 mg/L Co2+, Ni2+, MoO42–; ≤ 3 mg/L Cu2+.

Conversion table

Storage:
Store the test kit in a cool (< 25 °C) and dry place.
