Nov 01, 2019The TD tubes documented in most studies are 3.5 inches long, with an outer diameter of 1/4 inch or 6 mm and an inner diameter of 5 mm (stainless or inert-coated steel) or 4 mm (glass). The central length of the TD tube is approximately 60 mm, which may be packed with up to three or four sorbent beds to adsorb target compounds.Assessing Potential Indoor Air Impacts For Superfund Sites----- ASSESSING POTENTIAL INDOOR AIR IMPACTS FOR SUPERFUND SITES Contract No. 68D00124 Work Assignment 1-76 Prepared for U.S. Environmental Protection Agency Office of Air Quality Planning and Standards Research Triangle Park, North Carolina 27711 September 1992 Submitted by Pacific Environmental Services, Inc. 560 Herndon Parkway, Suite 200 Herndon, Assessment of Mitigation Systems on Vapor Intrusion TenaxTA stainless steel TD tube O D �� L 1 4 inch �� 3 1 ----- Table of Contents 1.0 Executive Summary 1-1 1.1 Background 1-1 1.2 Purpose and Objectives 1-1 1.3 Methods 1-2 1.4 Conclusions 1-3 1.4.1 Conceptual Site Model VOC Data 1-3 1.4.2 Mitigation System PerformanceRadon 1-3 1.4.3 Mitigation System PerformanceVOCs 1-4 1.4.4 Meteorological Effects on Vapor Intrusion 1-5 1.4.5 Preferential Pathways and Conceptual Site Model Helium Tracer TenaxTA stainless steel TD tube O D �� L 1 4 inch �� 3 1

Thermal Desorption Tubes. All Thermal desorption tubes are ¼ inch OD x 3½ inch L (6.35 OD x 89 mm L). Tubes are chemically conditioned before shipping; use within 6 months or recondition. Restocking fee applies. Each tube has a flow direction arrow and unique number. Method.Thermal Desorption Technical SupportJul 23, 2013Axial samplers Single-bed, ¼-inch O.D., 5 mm I.D. stainless steel or Silcosteel sorbent tubes with a 15 mm air gap between the surface of the sorbent and the sampling surface are used as standard for pumped monitoring (see above). However, these tubes were also designed, as long ago as 19794 to be used as axial format diffusive samplers.Thermal Desorption Technical SupportTD-GC. The tube is 3.5-inch long by 1/4-inch OD stainless steel with an internal diameter of 5.0 mm. In this case, the diffusion barrier is an air gap 15 mm deep by 0.193 cm2 surface area14. The air gap is defined by two stainless steel, 100-mesh gauzes - one in the sampling cap defining the sampling surface of the monitor and the other located in a groove on
