OrthoPhosphorus

This test method is a standard method for measuring orthophosphorus (reactive phosphorus) in water and wastewater samples. Orthophosphorus is the simplest form of phosphorus and a key nutrient contributing to eutrophication.

Nitrate

This test method is a colorimetric test procedure used for the determination of nitrate-nitrogen (NO₃-N) in water samples. It is commonly applied in environmental monitoring, wastewater treatment, and drinking water analysis.

Nitrate+Nitrite

This test method is an established analytical method for measuring the combined concentration of nitrate (NO₃-) and nitrite (NO₂-) nitrogen in water and wastewater samples. It is part of the Standard Methods for the Examination of Water and Wastewater.

Nitrite

This test method is a colorimetric test procedure used for the determination of nitrite-nitrogen (NO₂-N) in water samples. It is commonly applied in environmental monitoring, wastewater treatment, and drinking water analysis.
