Head Space Gas Sampling And Venting Method And Arrangement, And Filtering And Sampling Ports Used Therewith

US Patent:
6557428, May 6, 2003
Filed:
Aug 7, 2001
Appl. No.:
09/922943
Inventors:
Terry J. Wickland - Evergreen CO
Darold M. Popish - Golden CO
Gilbert Brassell - Golden CO
Fred L. Popish - Arvada CO
Mark A. Castagneri - Arvada CO
Michael D. Peterson - Parker CO
Assignee:
Nuclear Filter Technology, Inc. - Golden CO
International Classification:
G01N 100
US Classification:
7386474
Abstract:
A headspace gas sampling and venting method utilizes a vent port and a sampling port which are punched through the lid of a drum containing hazardous materials, such as transuranic waste. In accordance with the system, a punch having a hollow passage therethrough, which passage has a filter element therein is first inserted through the lid using a pneumatic gun. A second punch, similar to the first punch, but having a passage with a septa seal therein is thereafter inserted through the lid with the pneumatic gun. Headspace gas beneath the lid is then sampled with a needle inserted through the septa seal. Both the venting port and sampling port are configured with detachable punch points which pass through the lid and are then released from the venting and sampling ports so as to open ends of the passages therethrough for communication with the headspace. In a preferred embodiment of the invention, the punch points are held on the venting and sampling ports by annular plastic retainers which break when the ports are inserted through the drum lid, thus allowing detachable punch points to fall away.
