ALS offers expertise in high-resolution analyses for dioxins, furans, dioxin-like compounds, and polychlorinated biphenyls (PCBs) congeners.
ALS features sophisticated high-resolution gas chromatograph/high-resolution mass spectrometers (HRGC/HRMS) to perform high-resolution testing on a variety of matrices including, but not limited to: food products, sediments, animal tissues, water, soil, air, waste, household dust, and building products.
ALS features specialized laboratory equipment achieves 10-100 times lower detection limits than older instruments and is among the most sensitive in the industry. The HRGC/HRMS is an optimal choice for ultra low-level trace detection applications such as the analysis of dioxins, furans, and PCB congeners.
NORTH AMERICA
The high-resolution laboratory in the USA maintains a variety of certifications and accreditations with federal and state agencies and regulatory programs. Under the current NELAC program, we are able to perform high-resolution testing services in most states for air, water, wastewater, solid, and hazardous waste.
Table A gives the various analytical methods performed in the USA and the regulatory program to which they are typically associated.
ALS offers a range of electronic data deliverables (EDD). By generating a number of various deliverable formats, ALS is able to support data transfer into large relational database management systems. ALS also works closely with commercial clients to produce electronic data formats compatible with their systems.
EUROPE
ALS also has extensive expertise in in Europe for high resolution analyses for dioxin and dioxin-like compounds, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) congeners, and polybrominated diphenyl ethers (PDBEs), among other compounds.
The dedicated 525 square meters laboratory is located in the heart of Europe and features four sophisticated instruments high-resolution gas chromatograph/high-resolution mass spectrometers (HRGC/HRMS) to perform ultra-trace testing on a variety of matrices including, but not limited to: food products, feed stocks, sediments, water, soil, emission, air, waste, chemical products.
