About the Salicylate Method
The Salicylate Method (Hach Method 8155) is now more commonly used for ammonia nitrogen analysis in water and wastewater applications than the Nessler method. It provides sensitive low-range measurement capability for monitoring nutrient levels, and treatment performance. The salicylate method for ammonia also eliminates mercury-containing reagents
The salicylate colorimetric method produces a green-colored complex proportional to ammonia concentration, enabling reliable low-range ammonia measurements.
Benefits include:
• Mercury-free chemistry
• Excellent suitability for low-level ammonia monitoring
• Reduced interference from common hardness constituents
• Reduced hazardous waste handling requirements
• Consistent performance across water and wastewater applications
