Passive Diffusion Samplers Services
Beacon Environmental can target a broad range of compounds using sorbent filled stainless steel tubes to passively collect VOCs and SVOCs in soil vapor or indoor air following established ASTM methods, as well as other international protocols. Passive diffusion samplers do not require pumps or electricity and can be used to collect samples over a brief period of time (e.g., one hour) to weeks (e.g., 14 to 30 days), thereby providing a time-integrated concentration in units of ug/m3 or ppbv.
A broad range of VOCs and lighter SVOCs can be targeted using passive diffusion samplers and because the samplers can be exposed for extended time periods, low reporting limits in the sub-ppbv range are achieved. Passive diffusion samplers are analyzed by Beacon Environmental following EPA Method TO-17.
