Thumbnail Filmstrip of 1.5 x 3 inch Polyurethane Foam Substrate for Semivolatile Sampling (10/pk) Images
The TE-1015 polyurethane foam substrate is a vapor collection medium designed for sampling semivolatile organic compounds (SVOCs) from ambient air. This 1.5 x 3 inch foam plug provides efficient collection of semivolatile organic compounds with moderate to low vapor pressures, making it ideal for environmental monitoring and air quality assessment applications.
Technical Performance
Polyurethane foam is used worldwide for active and passive sampling of semivolatile organic compounds in air due to its efficiency for collecting a wide range of compounds with moderate to low vapor pressures. The uniformly porous structure allows gaseous chemicals to penetrate throughout the foam matrix, providing effective capture and retention of target analytes during sampling operations.
Specifications
- Dimensions: 1.5 inch × 3 inch
- Package quantity: 10 foam substrates per package
- Material: High-quality polyurethane foam
- Uniform porosity for consistent sampling performance
Applications
These polyurethane foam substrates are used to collect airborne particulate and vapor contaminants, including volatile organic compounds, airborne pesticides, and PFAS in ambient air. The substrates are designed to meet requirements for sampling using EPA methods TO-4A, TO-9A, and TO-13A. EPA TO-13A specifically addresses determination of semivolatile organic compounds in air and necessitates backup sorbent material to provide efficient collection of polycyclic aromatic hydrocarbons (PAHs).
Compatibility
The TE-1015 foam substrates are compatible with Tisch Environmental passive air samplers and high-volume air sampling systems designed for semivolatile organic compound collection. These foam plugs work in conjunction with particulate filters in dual-sampling configurations for comprehensive ambient air monitoring programs.
Sampling Guidance
Foam substrates should be pre-cleaned before deployment and handled with appropriate protective equipment to prevent contamination. Environmental factors such as temperature and sampling volumes affect sampling accuracy and capacity, requiring consideration of deployment conditions for optimal performance. Follow established protocols for foam preparation, deployment, and post-sampling handling to ensure data quality and regulatory compliance.
