Effluent Water
Monitoring water outflows from factories and daily living is very important for preventing water pollution. In particular, effluents from business operations that discharge water contaminated with hazardous substances harmful to our living environment must be managed according to strict standards.
Organic Phosphorus Compounds
Organic phosphorus compounds, which occur from organophosphorus pesticides or factory effluent water, can cause eutrophication due to an accumulation of phosphorus in lakes, ponds, or other closed bodies of water. Organic phosphorus compounds can be analyzed with high sensitivity using a gas chromatograph equipped with a flame photometric detector that can selectively detect phosphor compounds.
Alkyl Mercury Compounds
Due to the lipophilicity of highly toxic alkyl mercury compounds, they tend to concentrate in biological organisms and can cause central nervous system disorders in humans if ingested in high concentrations. Alkyl mercury compounds can be analyzed with high sensitivity and selectivity using a gas chromatograph mass spectrometer (GC-MS).

On-Line Water Quality Analyzers
Not all effluent water quality analysis is conducted in a laboratory. On-line analyzers are also used to continuously monitor factory effluents.
Shimadzu offers TOC, TNP, and other on-line analyzers for monitoring effluent water. Shimadzu also offers the maintenance services of instruments utilizing cloud system with TNP-4200 series, on-line total nitrogen and total phosphorus analyzers.
River Water and Seawater
It is also important to appropriately test the water quality of rivers, lakes, and seawater based on environmental standards specified for protecting human health and living environments. Shimadzu contributes to ensuring the safety of environmental waters by supplying analytical and measuring instruments for testing whether they meet specified water quality standards.
Volatile Organic Compounds (VOCs)
Benzene, dichloromethane, trichloroethylene, and other volatile organic compounds are organic pollutants that are harmful to our health. To prevent pollution of water environments, respective countries have specified environmental standards for drinking water, effluent water, and environmental waters.
VOCs are analyzed using a gas chromatograph mass spectrometer. Shimadzu offers the main pretreatment equipments used for measuring VOCs, such as headspace systems and purge and trap systems.
Surfactants
Most of the surfactants produced as ingredients for detergents and other products are either non-ionic or anionic, but due to the large quantities used, they are often detected in the environment. In particular, anionic surfactants, which originate from sources such as factory effluents and residential wastewater and can cause foaming when present in water, serve as an important pollution indicator. Such surfactants are analyzed using a liquid chromatograph or a liquid chromatograph mass spectrometer.
