Brent Pautler, Ph.D. (ON) will present “Patented Quantitative Passive Soil-Gas Monitoring with the Waterloo Membrane Sampler™” during Eurofins Environment Testing America Webinar Series at 1:30pm EDT on May 11, 2021.
Brent’s co-presenters are Heidi Hayes (Eurofins Air Toxics) and Todd McAlary, Ph.D. (Geosyntec Consultants).
Brent received his Ph.D. environmental analytical chemistry in 2013 where he gained advanced technical experience in spectroscopy, chromatography, mass spectrometry, passive sampling, and chemistry informatics. Throughout his career, he has worked with scientists, engineers, and consultants, applying his chemistry and information technology expertise to help them solve unique problems in the laboratory and the field. His role includes managing and advancing SiREM’s passive sampling portfolio, analytical testing services while supporting Photonics business development.
Eurofins Scientific, through its subsidiaries, is the world leader in food, environmental, pharmaceutical and product testing and AgroSciences services. They are a global independent market leader in testing and laboratory services for genomics, discovery pharmacology, forensics, advanced material sciences and for supporting clinical stidies. Additionally, Eurofins is emerging as a key player in specialty esoteric and molecular clinical diagnostic testing in Europe and USA.
Eurofins has more than 50,000 staff across independent companies, operating more that 800 laboratories in 50 countries and counting. Their facilities offer a portfolio of over 200,000 analytical methods to assess the safety, identity, composition, authenticity, origin and purity of biological substance and products, including innovative clinical diagnostic services.
Passive sampling has been growing in popularity for the measurement of volatile organic compounds (VOCs) due to lower costs, simpler sampling protocols and ease of deployment, with applications ranging from indoor/outdoor air quality and soil vapor intrusion assessments. The Waterloo Membrane Sampler™ (WMS™), a passive permeation sampler which incorporates a polydimethylsiloxane membrane across the face of a vial filled with sorbent medium, provides additional advantages such as a high resistance to water vapor and predictable uptake rates for virtually any VOC. It has found use in collecting time-weighted average quantitative results for soil gas and vapor intrusion projects for risk assessment and/or monitor remediation projects. This presentation will provide technical information on the WMS™ and provide data on sampler developments including the use of WMS™ in soil gas sampling programs in which the design of the sampler was modified to incorporate a thicker membrane, reducing the potential for “starvation”, a common issue when collecting soil gas samples with passive samplers. The benefits relative to the conventional Summa Canister/TO-15 methods of sampling and analysis will also be introduced.
