| titleOfInvention | Vapor trap system and associated method for detecting volatile organic chemical vapors |
| abstract | A vapor trap for detecting VOCs includes a housing, having a first end portion, a second end portion and at least one opening for receiving gas vapor. The housing is at least partially buried in ground with a vapor containment mechanism detachably connected to the first end portion of the housing. The vapor containment mechanism can be removed after a predetermined time period and replaced with a vapor sampling mechanism. An organic vapor analyzer can be connected in fluid relationship to the vapor sampling mechanism to measure VOCs. Optionally, a vacuum pump can be utilized to draw vapor into the vapor trap and then subsequently into the organic vapor analyzer. There can be a first selector valve located between the vapor sampling mechanism and the vacuum pump and a second selector valve located between the vapor sampling mechanism and the organic vapor analyzer. A preferred organic vapor analyzer is a photo-ionization detector. The method for detecting VOCs utilizing a vapor trap includes at least partially burying a housing in ground that includes a first end portion, a second end portion and at least one opening and sealing the housing with a vapor containment mechanism, e.g., plug. After a predetermined time period, the vapor containment mechanism is removed and replaced with a vapor sampling mechanism. The housing is buried in vapor transmissive material and applied with sealing material to the top portion of the housing to position the housing in a predetermined location. The vapor sampling mechanism is connected in fluid relationship with an organic vapor analyzer with an optional vacuum pump for drawing additional vapors from the housing into the organic vapor analyzer. |
