A new ASTM International standard will help calculate the amount of nitrogen in water samples in a more efficient way. The test method (soon to be published as D8083, Test Method for Total Nitrogen, and Total Kjeldahl Nitrogen (TKN) by Calculation, in Water by High-Temperature Catalytic Combustion and Chemiluminescence Detection) was developed by ASTM International's committee on water (D19).
Specifically, the test method helps measure the amount of total nitrogen and total dissolved nitrogen in surface water, seawater, groundwater, wastewater, and more.
