[Analysis Case] Evaluation of Nitrogen Components in Solution

It is possible to analyze inorganic nitrogen by form.

Nitrogen is utilized in various forms across a wide range of fields including chemistry, materials, food, and pharmaceuticals. Nitrogen compounds consist of inorganic nitrogen compounds such as nitrates, nitrites, and ammonia, as well as organic nitrogen compounds like amino acids. In the case of samples in aqueous solution, inorganic nitrogen compounds such as nitrate ions, nitrite ions, and ammonium ions can be evaluated using ion chromatography, while organic nitrogen can be assessed using HPLC or LC/MS. Total nitrogen, which includes both inorganic and organic nitrogen compounds, can be evaluated using spectrophotometry.
