Analytical Reagents News: Alfa Chemistry Starts to Provide Organic Pollutant Standards
To meet the increasing market demand for pollutant analytical standards and certified reference materials, Alfa Chemistry recently announced to offer a wide range of organic pollutant standards that may be used in the analytical testing of environment pollutants.
Organic pollutants include phenols, chlorinated phenols, endocrine disrupting chemicals, azo dyes, polyaromatic hydrocarbons, polychlorinated biphenyls, pesticides, etc. Over the last few decades, increasing numbers of water-soluble organic pollutants have been found in the environment. Environmental pollutants are of serious ecotoxicological and health concern worldwide.
The newly added product line of organic pollutant standards at Alfa Chemistry covers: air pollutants, aldehydes / DNPH standards, PCBs & dioxins standards, perfluoro compounds, phenol standards, plasticizers & phthalates, polycyclic aromatic hydrocarbon (PAH) standards, volatile & semivolatile standards.
Air Pollutants, Aldehydes / DNPH Standards
In the analysis of air pollutants, aldehydes/DNPH standards are mainly used for qualitative or quantitative analysis of aldehydes. The commonly used aldehydes/DNPH standards are acetaldehyde-2,4-DNPH, acrolein-2,4-DNPH, benzaldehyde-2,4-DNPH, n-butyraldehyde-2,4-DNPH, propionaldehyde-2,4-DNPH, valeraldehyde-2,4-DNPH and others.
PCBs & Dioxins Standards
PCBs and dioxins are organic pollutants that can seriously pollute the environment and harm the health of organisms. As reference materials, PCBs & dioxins standards can be used to detect PCBs and dioxins in food or water or fields, either qualitatively or quantitatively. The commonly used PCBs & dioxins standards include decafluorobiphenyl solution, PCBs in sediment, PCBs in soil, PCBs in transformer oil and others.
Perfluoro compounds standards are used to analyze the perfluoro compounds in the surfactants, packaging materials and artificial blood. The commonly used perfluoro compounds standards include carbon tetrafluoride, 2,4,6-tris(trifluoromethyl)-1,3,5-triazine, 1,1,2-trichloro-1,2,2-trifluoroethane, 1,1,2-trichloro-1,2,2-trifluoroethane, pentadecafluorooctanoic acid and others.
Phenol standards possess high purity and determined characteristic values and are generally used in detection and analysis fields such as calibration of instruments, evaluation of test methods, qualitative analysis and quantitative analysis. The commonly used phenol standards include EPA phenols mixture, 2,3,5,6-tetrachlorophenol, 4-nitrophenol, 3-methylphenol, 4-chloro-3-methylphenol and others.
Plasticizers & Phthalates
Toys, food packaging bags, wallpaper, medical blood bags, medical hoses, detergents and many other products may possibly contain two harmful substances: plasticizers and phthalates. To make sure these products are safe for consumers, plasticizers & phthalates standards are needed to specify content, use and recycling methods.
More than 200 polycyclic aromatic hydrocarbons (PAH) have been detected in the environment. The PAH standards provided by Alfa Chemistry can be used to analyze PAHs in river sediments, rubber products and atmosphere.
Volatile & Semivolatile Standards
Volatile & semivolatile standards are often used as standard materials in various detection methods to detect volatile and semivolatile organic pollutants, which is of great significance for the protection of the environment and the health of organisms. The commonly used volatile & semivolatile standards include chlorodibromoacetic acid, 2,3-butanedione, 2-butanol, acrylonitrile, ethylbenzene and others.
