Ferrozine reagents for iron

Powders, prepared solutions and reagent kits for a defined iron-analysis method.

Specify the iron result you need

PMA supplies ferrozine as a powder, a prepared solution or part of a reagent kit. The right choice depends on the method, instrument and preparation sequence in use.

Ferrozine forms a coloured complex with ferrous iron, Fe(II). Measurement of ferric iron or a total-iron fraction requires the appropriate reduction and sample-preparation steps in the method.

Choose the form of supply

Ferrozine powder

For laboratories working to their own defined preparation procedure. Confirm the required specification and quantity.

Prepared solutions

Bring the formulation, concentration and packaging requirements together for a ready-prepared supply.

Instrument reagent kits

Match the complete reagent set to the analyser, method and measuring range; include the existing kit reference.

From colour development to an iron result

The ferrous–ferrozine complex produces a strong magenta colour. The analytical method measures the absorbance of that complex and uses calibration to relate it to iron concentration.

Reaction conditions and preparation are part of the measurement. Send PMA your method reference, required iron fraction and any instrument details when requesting a replacement kit or a custom formulation.

Our existing application experience includes Tytronics Sentinel instruments. Compatibility must be checked against the installed method and range, particularly when replacing an older preparation.

A question worth asking

Does ferrozine directly measure ferric iron?

The coloured complex forms with ferrous iron. A method intended to include ferric iron needs a suitable reduction step, and the reported iron fraction also depends on sample preparation. Follow the validated procedure for your application.
