Glycine p-toluenesulfonic acid is an essential standard for ensuring accurate and reliable results in water quality testing, particularly for total nitrogen (TN) and total Kjeldahl nitrogen (TKN) analyses. In water analysis, TN recovers multiple forms of nitrogen, including organic nitrogen, ammonia (NH₃), ammonium (NH₄⁺), and nitro compounds such as nitrate (NO₃-) and nitrite (NO₂-). This comprehensive recovery is critical for assessing the total nitrogen content of water samples.

TKN analysis, a common test in wastewater treatment, measures the sum of organic nitrogen, ammonia (NH₃) and ammonium (NH₄⁺). It provides a detailed understanding of nitrogen levels in water, which is essential for maintaining water quality and ensuring compliance with environmental standards. Glycine p-toluenesulfonic acid, which contains 5.665% nitrogen and 35.40% crude protein, serves as a reliable protein TKN standard to enhance the accuracy of these measurements.

This product is available in a 25g bottle. For more comprehensive testing, product 2277800 offers a complete set of nitrogen digestion standards with different digestion resistances to ensure accurate and consistent results in water quality analysis.
