Low Range Manganese Testing for Drinking Water, Wastewater and Industrial Applications
The Manganese Reagent Set, LR, PAN, 10 mL (2651700) provides accurate, low-range measurement of manganese (Mn) in water using the proven PAN colorimetric method.
Designed for use with Hach lab and portable spectrophotometers, this method delivers rapid, sensitive manganese analysis across the range of 0.006 - 0.700 mg/L Mn.
The method uses 1-(2-Pyridylazo)-2-Naphthol (PAN) chemistry to reduce manganese to Mn²⁺, mask interfering metals, and form a distinct, orange-colored complex that is measured photometrically at 560 nm. The result is reliable manganese testing for both laboratory and field water analysis applications.

Kit format optimised for:
• Hach spectrophotometers
• Standardised testing workflows
• Reduced reagent handling
• Improved consistency between operators
An alkaline-cyanide reagent masks common metal interferences such as:
• Iron
• Copper
• Other transition metals
This improves accuracy in complex water matrices including wastewater and industrial samples.
Kit format optimized for:
• Hach spectrophotometers
• Standardized testing workflows
• Reduced reagent handling
• Improved consistency between operators
The PAN method uses 1-(2-Pyridylazo)-2-Naphthol to detect manganese in water samples.
Test Process:
1. All manganese is reduced to soluble Mn²⁺
2. Interfering metals are masked using an alkaline-cyanide reagent
3. PAN reacts with manganese to form an orange-colored complex
4.The sample is measured photometrically at 560 nm
5. Color intensity is proportional to manganese concentration
This method provides accurate low-range manganese analysis with excellent repeatability.
Please note: Digestion is necessary for total manganese determinations in some sample matrices.
