The Vapor Pin® Capsule was developed to house the Waterloo Membrane Sampler™ – Vapor Pin® (WMS™-VP) produced by SiREM. The WMS™-VP, a passive permeation sampler, will allow you to quantitatively measure time-weighted average concentrations of volatile organic compounds (VOCs) in soil gas.
Introducing the New Quantitative Sub-Slab Passive Sampler with WMS™ and the Vapor Pin® Sampling Device. As a leader in passive sampling technology, SiREM is excited to introduce the Waterloo Membrane Sampler™ – Vapor Pin® (WMS TM -VP), a new WMS™ configuration developed in collaboration with Vapor Pin Enterprises, Inc., in Plain City, Ohio and Eurofins Environment Testing Northern California that brings together the best of two advanced technologies for sub-slab sampling. The innovative integration of the WMS TM (the passive permeation sampler for time-weighted average concentration measurement of VOCs) and Vapor Pin® samplers (the versatile sampling device used to facilitate the collection of soil gas samples and pressure measurements beneath any hard service or engineered vapor intrusion barriers) creates a powerful and versatile solution designed to revolutionize environmental monitoring, site characterization, and gas evaluation processes.
