Dioxins, furans and PCBS
Determination of organic micro-pollutants persistent emission, soil, water, food and waste by means of instrumental techniques with high sensitivity and resolution. LAB has a department dedicated to these determinations and uses systems HRGC/HRMS, GC-MS/MS and GC/Q-TOF for the analysis of PCDDS, PCDFS and PCBS on the arrays a different
Determination of dioxins, furans and PCBS
Dioxins (PCDD), furans (PCDFS) and polychlorinated biphenyls (PCBS) belong to the category of persistent organic contaminants and may be present even at extremely low concentrations. Their determination requires a high level of selectivity, analytical, control and interference, and the ability to distinguish and quantify the individual congeners.
The analysis allows to define the profile congenerico of the sample and, when applicable, to determine the PCB indicators and dioxin-like PCBS and calculate the relative toxicity equivalent (TEQ). The result can be used for compliance testing, characterization of the contamination and environmental monitoring, or process.
Object parameters analysis
The analytic plan is defined as a function of the matrix and of the specific objective of the investigation, identifying the groups of compounds and the congeners to determine.

Analysis at trace levels
The determination of dioxins, furans and PCBS requires the ability to measure very low concentrations in complex matrices. The preparation and purification of the sample are then driving steps to reduce the interference and get the correct separation of the compounds from the search.
The high selectivity of the instrumental techniques allows the identification and quantification of individual congeners, distinguishing it from other substances present in the sample, and providing the level of detail required by the different analytical applications.
When the need for analysis of dioxins, furans and PCBS
The determination of PCDDS, PCDFS and PCBS is required when it is necessary to check the presence of persistent organic contaminants at very low concentrations, in the context of environmental controls, production or compliance. The choice of the congeners are looking for, and limits of quantification depends on the matrix, the purpose of the investigation and the legal framework applicable.
These analyses are applied, for example, in the control of industrial emissions, the characterization of waste and soil, in the verification of environmental contamination and control of food and other complex matrices. May also be required to deepen abnormal situations, evaluation of the source of contamination or follow the effectiveness of interventions and treatment processes.
