PCBs & dioxins standards are a class of reference materials that have one or more definite eigenvalues. PCBs & dioxins standards may be pure substances or mixtures of several chemicals, but all have high purity. PCBs and dioxins are organic pollutants that can seriously pollute the environment and harm the health of organisms. Therefore, it is necessary to use PCBs & dioxins standards to test PCBs and dioxins. As reference materials, PCBs & dioxins standards can be used to detect PCBs and dioxins qualitatively or quantitatively. Commonly used PCBs & dioxins standards include decafluorobiphenyl solution, PCBs in sediment, PCBs in soil, PCBs in transformer oil and others.
Analyzing PCBs and dioxins of water: PCBs and dioxins in drinking water and waste water can be measured with PCBs & dioxins standards to ensure water quality. The most commonly used methods are gas chromatography and liquid chromatography, in which PCBs & dioxins standards are essential. In the detection process, the PCBs & dioxins standards are used to make the standard curves. According to the peak position and peak strength of the standard curves, the qualitative and quantitative determination of the PCBS and dioxins can be realized.
Analyzing PCBs and dioxins of food: In order to ensure food safety, it is necessary to test the content of PCBs and dioxins in food. In order to achieve a more accurate analysis of the type and content of PCBs and dioxins, the PCBs & dioxins standards are the key. For example, PCBs & dioxins standards can be used to detect a variety of PCBs and dioxins substances in aquatic products such as tilapia by gas chromatography-mass spectrometry. In addition, this method has the advantages of fast speed and high accuracy.
The others: Apart from the above two fields, PCBs & dioxins standards can also be used in many fields, including analyzing PCBs and dioxins of paper products, textiles, soil, feed, air and many others.
