Bottle-Vac™ – Helium Diffusion Sampling
Using Helium Diffusion Sampling into Silonite® Canisters and Bottle-Vacs™ for indoor air monitoring has never been so easy and cost effective!
Using Helium Diffusion Sampling into Silonite™ Canisters and Bottle-Vacs™ for indoor air monitoring has never been so easy and cost effective! Introducing Entech’s low-cost external HDS™ Samplers that allow any Silonite™ Canister or Bottle-Vac™ to be used to perform time integrated sampling both simply and cost-effectively. HDS™ utilizes a simple diffusion zone to control the exchange rate of helium and air, with diameters that are 20–50 times larger than typical critical orifice samplers, making particulate plugging virtually impossible.
