Ultra-trace and Toxicology

AGAT Laboratories offers Ultra-trace analysis of Persistent Organic Pollutants (POPs) such as Dioxins and Furans, PCBs and PAHs via Gas Chromatography/High Resolution Mass Spectrometry. Our Ultra-trace, Toxicology and Specialty Analysis operations are accredited by CALA, the SCC and the Ministère de l’Environnement et de l’Action en matière de changement climatique (MDDELCC) for specific tests.
 
Natural processes such as bioaccumulation and biomagnification can concentrate many of these compounds, increasing their threat to living organisms in the environment. For this reason, low-level detection of these pollutants is important.

Our Analytical Services

AGAT Laboratories is capable of providing high resolution, analytical results for the testing of Dioxins, Furans, PCBs and PAHs in varied environmental matrices including:

  • Soil/sediment
  • Tissue/biological
  • Ground/surface water
  • Drinking water
  • Air

Our Ultra-trace, Toxicology and Food Testing Divisions also provide services geared toward the Life Sciences sector. These services include LC-MS-MS technology and some additional GCMS instrumentation.

This technology will be designed to test for the following parameters:

  • Drugs of abuse in blood and urine.
  • Perchlorates in environmental samples.
  • Nonylphenol Ethoxylates and pharmaceuticals in environmental samples.
  • Additional vitamins and sugars in food samples.
  • Comprehensive Pesticide Residue Screening in food samples.
  • Antibiotics in food, blood and urine samples.
  • Mycotoxins and melamine in food samples and containers.

Our Instrumentation

AGAT Laboratories utilizes High Resolution Mass Spectrometer (HRMS) for our ultra-trace testing. With these instruments available in Eastern and Western Canada, we process samples in a turn-around time of 15 days. Additionally, we have the resources to take on rush-orders in which the turn-around time is 5 to 7 days, depending on the number of samples.
 
With the HRMS, data results are uncompromisingly accurate to levels at or above detection limits. This results from using exact masses for detection compounds. We use a total of four exact masses to positively identify a compound.

Our Trace Organics Experience 

AGAT Laboratories' experience includes many projects with analytical work for underground storage tanks, pesticide residues in many applications, PCBs for utilities and hygiene, identification of unknowns for waste classification, solvent scans for landfill purposes, organic halide determinations, materials stability studies, organic vapour determinations, product purity, groundwater monitoring and many others.

Certain environmental situations call for a direct assessment of toxic effects upon specific types of organisms. This testing is very broad and shows the potential effects of releasing substances into the environment, usually through waterways. Organisms such as rainbow trout, daphnia magna and microtox (bioluminescent bacteria) may be destroyed by the improper release of toxins.

Exposing these organisms to the solution to be released will prove if a toxic effect will potentially occur. In this way, negative effects take place in the lab on an extremely small scale rather than in nature on a large and catastrophic scale.

Clients utilizing these services include oil and gas companies, manufacturing companies, waste treatment facilities, materials safety personnel, airports, recyclers and a variety of other organizations. The professionals in this area also focus on microbiological work such as the assessment of total and fecal coliforms, bacterial identification, enumeration and total plate counts.
