Nitrogen Analyzer / Total Nitrogen Analyzer (TN Analyzer)

The element nitrogen can be found throughout nature and in a variety of man-made compounds. Nitrogen analyzers / total nitrogen analyzers can reveal important information on everything from fertilizers, water quality, food, plant biology, and more. These instruments, which are often combined with other types of elemental analyzers, measure evolved gases that emerge following thermal decomposition of a sample. Among the features to look for in a nitrogen analyzer are whether it detects organic or inorganic nitrogen, the measurement range, measurement time, throughput, sample states measured, and software.
