Organic Nitrogen [Water]

This test method is a standard method used to measure organic nitrogen concentrations in water and wastewater samples. Organic nitrogen refers to nitrogen bound within organic compounds, distinct from inorganic nitrogen forms like ammonia or nitrate.

pH

This test method is a Standard Methods procedure for measuring pH in water and wastewater samples using a pH meter.

Phosphorus [Soluble]

This test method is used in determining phosphorus in water. This test is important to help monitor phosphorus levels in water to avoid eutrophication and damage to aquatic ecosystems.

Phosphorus [Total]

This test method is used in determining orthophosphate (and, when preceded by proper digestion, total phosphorus) in water. This test is important to help monitor phosphorus levels in water to avoid eutrophication and damage to aquatic ecosystems.

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.

Minerals [Soluble]

This test method is an official U.S. Environmental Protection Agency (EPA) procedure for the determination of metals and trace elements in a variety of water and waste samples using Inductively Coupled Plasma–Optical Emission Spectrometry (ICP-OES). This test method quantifies soluble calcium, copper, iron, magnesium, manganese, phosphorus, potassium, sodium, sulfur, and zinc.

Minerals [Water] ICPOES

This test method is a standardized analytical procedure for the quantitative determination of minerals in water samples using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). The method is widely employed for monitoring metal contaminants in drinking water, surface water, groundwater, and wastewater. This test method quantifies calcium, copper, iron, magnesium, manganese, phosphorus, phosphorus (as P2O5),… Continue reading Minerals [Water] ICPOES

Metals ICPMS [WW KED mode] all except Al, B

This test method is a widely used analytical procedure for the quantitative determination of trace metals and elements in various water and wastewater samples using Inductively Coupled Plasma Mass Spectrometry (ICP-MS). This method is recognized for its high sensitivity and precision, allowing for the detection of metals at ultra-trace levels. This test method quantifies antimony,… Continue reading Metals ICPMS [WW KED mode] all except Al, B
