ASTM D8083

Standard Test Method for Total Nitrogen, and Total Kjeldahl Nitrogen (TKN) by Calculation, in Water by High Temperature Catalytic Combustion and Chemiluminescence Detection

Applicability: ASTM D8083 is a test method for determining total nitrogen (TN) and total Kjeldahl nitrogen (TKN) in water samples. It’s applicable to various water sources like surface water, seawater, groundwater, and wastewater. The method uses high-temperature catalytic combustion and chemiluminescence detection, suitable for measuring nitrogen concentrations within a range of 0.2 to 10 mg/L N.

Purpose: The primary goal of ASTM D8083 is to accurately measure the concentration of nitrogen in water samples, which is essential for understanding water quality and managing potential environmental impacts.
