Lovibond® Nessler Reagent

Lovibond® Nessler Reagent is a high-sensitivity liquid reagent system designed for the colorimetric determination of ammonia nitrogen (NH₃-N) in water samples. This reagent plays a critical role in water quality testing, environmental monitoring, and wastewater treatment, forming a yellow to brown color complex in the presence of ammonia, which is measured photometrically.

The Nessler method relies on multiple reagent components applied in a specific order, and the accuracy of test results depends heavily on the precise number and size of drops added. As such, consistent technique and careful handling are essential for reproducibility and reliability.

Key Features

• Target Parameter: Ammonia (NH₃-N) in aqueous samples
• Measurement Ranges Supported:
  • 0.02 – 0.2 mg/L N (Method No. M3007)
  • 0.2 – 0.52 mg/L N (Method No. M3008)
  • 0.56 – 1.2 mg/L N (Method No. M3009)
  • 1.2 – 2.0 mg/L N (Method No. M3010)
• Optimized for Lovibond® Systems: Designed for use with Lovibond® photometers and comparators.
• High Precision Required: Reagent drop volume and order of addition critically affect test results.
• Ready-to-Use Liquid Form: No need for additional mixing or preparation.

Handling & Storage

• Store in a cool, dry place away from direct sunlight and high temperatures.
• Minimize oxygen exposure by closing the reagent bottle immediately after use.
• Shelf life is influenced by air exposure and environmental conditions, so handle with care to maintain accuracy and reactivity.
