Environmental Laboratory

Equipment and technologies

Analytical techniques for the determination of dioxins and other persistent organic pollutants:

• Analysis of environmental matrices: atmospheric emissions and immissions, water, leachate, waste, ash and biome, among others:
  • Dioxins and furans (PCDD/F)
  • Polychlorinated biphenyls (DL-PCB and NDL-PCB)
  • Polycyclic aromatic hydrocarbons (PAH)
  • Cyanotoxins (microcystins, anatoxins, etc.)

• Analysis of human and animal food products, including meat, fish, oils, eggs, milk, vegetables and mineral additives, among others:
  • Dioxins and furans (PCDD/F)
  • Polychlorinated biphenyls (DL-PCB and NDL-PCB)

Xevo TQ-XS (Waters). In 2025, the IQS Environmental Laboratory has incorporated a state-of-the-art triple quadrupole mass spectrometer, the Waters Xevo TQ-XS, into its analytical capabilities. With exceptional sensitivity and cutting-edge technology, this instrument enables ultra-trace level quantification of various contaminants across a broad range of environmental matrices. Its optimized design allows for high-speed scanning without compromising resolution, ensuring consistent mass accuracy and precision in every analysis. Additionally, the Xevo TQ-XS seamlessly integrates with liquid chromatography (LC) for the analysis of polar contaminants and gas chromatography (GC) for the detection of non-polar and volatile contaminants, providing a versatile and high-performance analytical solution.
