Volatile & semivolatile standard is an important branch of standard materials. As physical standards, volatile & semivolatile standards have one or more specific values that can be used to calibrate instruments, evaluate test methods, qualitatively and quantitatively analyze substances and others. Volatile & semivolatile standards can be either a pure substance or a mixture of substances, but both are highly pure. 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. In general, commonly used volatile & semivolatile standards include chlorodibromoacetic acid, 2,3-butanedione, 2-butanol, acrylonitrile, ethylbenzene and others.
Analysis of volatile and semivolatile organic pollutants in soil: The content of volatile and semivolatile organic pollutants in soil is related to the environment and the health of organisms, so it needs to be strictly controlled. Volatile and semivolatile organic pollutants in soil, such as benzene series, phenols, anilines, nitroaromatic hydrocarbons, chlorinated aromatic hydrocarbons, polycyclic aromatic hydrocarbons and phthalates, can be detected by volatile & semivolatile standards. For example, using volatile & semivolatile standards, sixteen trace volatile and semivolatile organic pollutants in soil can be detected by high performance liquid chromatography, and this method has the advantages of high efficiency, convenience and sensitivity.
Analysis of volatile and semivolatile organic pollutants in drinking water: The residual volatile and semivolatile organic pollutants in drinking water will cause great harm to human health, so it is necessary to use volatile & semivolatile standards to detect them. The commonly used detection methods are high performance liquid chromatography and gas chromatography. In the detection process of these two methods, volatile & semivolatile standards are essential. The main function of volatile & semivolatile standards is to draw the standard curves, which is the basis of subsequent quantitative and qualitative analysis.
Analysis of volatile and semivolatile organic pollutants in indoor air: Indoor new building materials and daily cosmetics are widely used, which will release a lot of volatile and semivolatile organic pollutants. These volatile and semivolatile organic pollutants can seriously affect human health. Many countries and organizations have strict regulations on the content and types of indoor volatile and semivolatile organic pollutants. Therefore, in order to achieve better quantitative and qualitative detection of those organic pollutants, volatile & semivolatile standards are necessary. For example, in gas chromatographic detection, according to the peak positions and the peak strengths of the standard curves drawn by volatile & semivolatile standards, the detection of the samples can be realized.
Others: In addition to the above fields, volatile & semivolatile standards can also be used in a number of other fields, including the detection of volatile and semivolatile substances in furniture, factory waste water, solid waste and others.
