UV total nitrogen analyzer 5B-3BN
Total nitrogen, abbreviated as TN, is one of the important indicators for measuring water quality. The definition of total nitrogen is the total amount of various forms of inorganic and organic nitrogen in water. Including inorganic nitrogen such as NO3, NO2, and NH4, as well as organic nitrogen such as proteins, amino acids, and organic amines, calculated in milligrams of nitrogen per liter of water. It is often used to indicate the degree of nutrient pollution in water bodies.
Total nitrogen is now generally measured using ultraviolet spectrophotometry. The 5B-3BN (V8.0 version) total nitrogen analyzer is a specially developed instrument for measuring total nitrogen. It uses ultraviolet spectrophotometry for measurement and has the characteristics of high measurement accuracy, wide range, simple operation, and easy mastery. The instrument has received high praise from many testers since its debut!

In theory, total nitrogen=ammonia nitrogen+nitrite nitrogen+nitrate nitrogen+organic nitrogen. Ammonia nitrogen=Kjeldahl nitrogen - organic nitrogen. Ammonia nitrogen+nitrous+nitrate nitrogen<total nitrogen. Sometimes, the total nitrogen value detected in the same water sample may be lower than the ammonia nitrogen value. The UV method for measuring total nitrogen is currently the most commonly used method!
