PTFE filters designed for polychlorobenzenes adhere to stringent specifications to ensure accurate sampling and analysis. Specifically, 13mm PTFE filters comply with NIOSH Method 5517 and CDC guidelines, which are critical for occupational safety and environmental monitoring. These filters are optimized for capturing airborne polychlorobenzenes, a group of hazardous compounds, with high efficiency and minimal interference. The specifications ensure reliability in laboratory and field settings, making them suitable for regulatory compliance and health risk assessments.
Key Points Explained:
-
Compliance with NIOSH Method 5517
- NIOSH Method 5517 is a standardized protocol for sampling and analyzing polychlorinated biphenyls (PCBs) and related compounds, including polychlorobenzenes.
- PTFE filters meeting this specification are validated for particulate retention and chemical compatibility, ensuring no degradation or adsorption issues during sampling.
-
Adherence to CDC Guidelines
- The Centers for Disease Control and Prevention (CDC) provides supplementary recommendations for occupational exposure monitoring.
- These guidelines emphasize filter efficiency, flow rate compatibility, and minimal sample loss, which PTFE filters fulfill due to their inert properties.
-
13mm Filter Size
- The 13mm diameter is a common standard for air sampling cassettes, balancing sufficient surface area for particle collection with practical handling in analytical workflows.
- This size is compatible with most personal air sampling pumps used in industrial hygiene studies.
-
Material Advantages of PTFE
- Polytetrafluoroethylene (PTFE) is chemically resistant to polychlorobenzenes, preventing filter breakdown or analyte interaction.
- Its hydrophobic nature minimizes moisture interference, critical for gas-phase sampling in humid environments.
-
Application in Polychlorobenzene Monitoring
- These filters are deployed in workplaces (e.g., chemical manufacturing) and environmental studies to assess exposure levels.
- Their compliance with NIOSH/CDC standards ensures data validity for regulatory reporting and health risk evaluations.
For purchasers, selecting PTFE filters with these specifications guarantees alignment with federally recognized methods, reducing compliance risks and ensuring data integrity. The combination of material robustness and standardized performance makes them a reliable choice for hazardous compound monitoring.
