3 Inch Polyurethane Foam Vapor Collection Substrate (Unwashed), 10/pk SKU: TE-1010

The TE-1010 polyurethane foam vapor collection substrate provides reliable adsorption media for sampling semi-volatile organic compounds, pesticides, and polychlorinated biphenyls (PCBs) in ambient air monitoring applications. Each 3-inch foam plug is specifically designed for use in Tisch Environmental's TE-PUF sampling systems, delivering consistent performance for EPA-compliant air quality assessments.

Technical Performance

The polyurethane foam matrix efficiently adsorbs chemicals from ambient air in high volume sampling applications, making it ideal for capturing target analytes across extended sampling periods. The foam substrate is white when new and may yellow upon exposure to light, though color change does not affect collection efficiency. This unwashed foam requires pre-cleaning before use to remove potential contaminants.

Key Specifications

• Length: 3 inches (76 mm)
• Package quantity: 10 foam plugs per package
• Condition: Unwashed (requires pre-cleaning)
• Material: Open-cell polyurethane foam
• Compatible flow rates: Up to 280 liters per minute

EPA Method Compliance

This substrate supports EPA Method TO-4A sampling procedures for pesticides and PCBs in ambient air, enabling laboratories to meet regulatory requirements for environmental monitoring. The high-volume sampling approach typically operates at approximately 8 cfm for 24-hour sampling periods, providing sufficient sample mass for accurate analytical detection.

System Compatibility

The TE-1010 foam plugs fit into glass cartridges within the lower chamber of Tisch Environmental's dual-chambered sampling modules. Tisch Environmental recommends the 3-inch TE-1010 plug for standard applications, with 2-inch (TE-1011) and 1-inch (TE-1012) alternatives available for specific sampling requirements. The foam substrate works in conjunction with particulate filters in the upper sampling chamber.

Applications

• Pesticide monitoring in rural and urban environments
• PCB assessment near electrical equipment and industrial sources
• Semi-volatile organic compound sampling
• Indoor air quality investigations
• Source emission characterization

Preparation and Handling

As unwashed foam, the TE-1010 substrate requires thorough pre-cleaning with appropriate solvents before deployment to remove manufacturing residues and potential interferents. Following 24-hour sampling periods, the foam cartridge should be returned to the laboratory for solvent extraction and analysis by gas chromatography with appropriate detectors. Proper chain-of-custody procedures ensure sample integrity throughout the monitoring process.
