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® (WMSTM-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 WMSTM (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.

Key Features and Advantages

  1. Time-Weighted Average Concentration Measurement – WMSTM-VP allows for precise and continuous monitoring of VOC concentrations over extended periods. This feature ensures that you obtain comprehensive data regarding VOC levels, enabling a deeper understanding of contaminant behaviors and trends.
  2. Versatile – Switch between active and passive sampling through a single WMSTM-VP sampling device.
  3. User Friendly – The user-friendly system of WMSTM-VP simplifies the setup and deployment process, allowing for easy operation even by non-specialists.
  4. Discrete Design – The product can incorporate the Vapor Pin® sampling device with a stainless-steel cover, concealing the sampling device in the sub-slab and providing a sleek and seamless outward appearance.

Are you ready to explore the future of environmental monitoring and sub-slab passive sampling?
