Macherey Nagel 91313 QUANTOFIX Nitrate/Nitrite
The Macherey Nagel 91313 QUANTOFIX Nitrate/Nitrite designed for rapid determination of nitrate (NO₃⁻) and nitrite (NO₂⁻) in water samples. Therefore, they are highly suitable for environmental monitoring, agriculture, water treatment, and laboratory screening where fast and reliable nitrogen compound analysis is required. Moreover, these strips utilize the modified Griess reaction for nitrate and the Griess reaction for nitrite, ensuring accurate and consistent detection.
In addition, the strips provide a clear color change from white to red-violet for both parameters, allowing easy visual interpretation. As a result, users can quickly estimate nitrate and nitrite concentrations using the provided color scale. Furthermore, the strips are compatible with QUANTOFIX Relax reflectometers, enabling more precise and objective instrumental readings when required.
Key Features
- Dual-Parameter Measurement
First, the strips measure both nitrate and nitrite simultaneously. Therefore, they provide a comprehensive analysis in one test. - Fast and Efficient Testing
Moreover, the strips enable rapid detection without complex procedures. Thus, they are ideal for on-site and routine applications. - Clear Colorimetric Results
In addition, the color transition from white to red-violet ensures easy and reliable interpretation of results. - Reflectometer Compatibility
Furthermore, the strips can be evaluated using QUANTOFIX Relax reflectometers. As a result, users can obtain accurate and consistent measurements. - Wide Measurement Range
Additionally, the test covers nitrate up to 500 mg/L and nitrite up to 80 mg/L. Therefore, it is suitable for various water quality conditions. - No Additional Reagents Required
Moreover, the strips are ready to use without extra chemicals. Consequently, testing becomes faster and more convenient. - Compact and Portable Design
In addition, the lightweight packaging makes it easy to carry for field testing and routine inspections. - Long Shelf Life
Finally, the product offers a shelf life of up to 2.5 years when stored properly. Therefore, it is suitable for long-term use. - Specifications
