Overview
Photometer Conventional Reagents are a family of Reagents for the measurement of the concentration of different chemicals, designed for a variety of analytical needs. These Reagents are capable of reacting with the target chemical in a photometer, providing accurate measurement results. HI93721-01 is a pre-measurement high mass Iron Reagent that allows users to achieve fast and accurate Colorimetric measurements for samples with the expected range of 0.00 to 5.00 ppm iron.
Features
1. Pre-measurement to ensure fast and accurate Colorimetric measurement
2. High-mass Reagents for Reliable Test Results
3. Specially designed for photometers, with strong compatibility
4. The number of tests is 100, which is economical and practical
5. Adaptation to USEPA Method 315B and Standard Method 3500-Fe B
Principle
HI93721-01 Reagent is based on the o-diazephedrine method and requires a Reagent that contains both a reducing agent and a complexing agent. This Reagent converts all forms of iron present in the sample to a ferrous (Fe2 +) or soluble state. When added to a sample containing iron, the Reagent causes the sample to turn orange; the greater the concentration, the deeper the Color. The intensity of the Color is determined by a compatible photometer and the concentration is shown as total iron in mg/L (ppm).
Applications
Water quality analysis, environment monitoring
Standards
USEPA method 315B (o-phenanthrene method), standard method 3500-Fe B
Steps
1. Preparation of Sample and HI93721-01 Reagent
2. Add Reagent to Sample
3. Observe Sample Color Change (Orange)
4. Color intensity measurement using compatible photometers
5. Read and record the total iron concentration in mg/L (ppm)
Notice
Only for samples with an expected iron concentration in the range of 0.00 to 5.00 ppm
• Must use a compatible photometer for measurement
• Follow Reagent's Safe Use Instructions
Store under Appropriate Conditions to Maintain Reagent Stability
