Hanna Instruments® Iron High Range Reagents, 300 tests, HI93721-03

Features:

• Appearance:  ivory powder
• CAS Nos.: 
  • Sodium Metabisulfite:  7681-57-4
  • Sodium Dithionite:  7775-14-6
  • 1,10-Phenathroline:  5144-89-8
• High quality reagents that are pre-measured, allowing for fast and accurate colorimetric determination of iron
• To be used with a compatible benchtop or portable photometer
• Manufactured in state-of-the-art facility and are clearly marked with  lot number and expiration date on each bottle and packet for traceability
• Follow an adaptation of the USEPA method 315B (phenanthroline method) and Standard Method 3500-Fe B
• Method requires reagent to contain both reducing and complexing agents that converts all but very most resistant forms of iron present in sample to the ferrous (Fe²⁺) or soluble state
• When reagent is added to sample containing iron, it will turn sample an orange hue—intensity of hue is measured with compatible benchtop or portable photometer and based upon the meter will be displayed in mg/L (ppm) as total iron
• Reagents are designed to be used with samples with expected range of 0.00 to 5.00 ppm iron
