Supelpak^™-2 4PFAS 20-40 mesh

Amberlite^™ XAD-2 resin is and has been crucial for collecting air contaminants. This polymeric adsorbent captures volatile organic compounds in air samples, enabling accurate assessments of environmental pollutants. However, its effectiveness relies heavily on a thorough cleaning process, which can be complex and involves multiple solvent washes and drying phases to eliminate residual contaminants that could compromise analytical results.

We are committed to bringing you Greener AlternativeProducts. This product is a Design for Sustainability (DfS) developed product,which belongs to one of the four categories of greener alternatives. Click hereto view its DfS scorecard.

Supelpak^™-2 4PFAS is designed specifically for EPA Other Test Method 45 (OTM-45): Measurement of Selected Per- and Polyfluorinated Alkyl Substances from Stationary Sources. This resin has been rigorously tested for background PFAS levels (CoA is listed with testing levels for the analytes within OTM-45). Integrating the ready-to-use Supelpak^™-2 4PFAS into your air sampling protocols will streamline processes and enhance the accuracy of PFAS analyses.

PFAS Cross-Contamination Prevention Notice
This product has been tested for per- and polyfluoroalkyl substances (PFAS). Users should pay special attention to avoid cross-contamination due to the prevalenceof PFAS related chemicals in consumer products, equipment, and in the environment.
Some best practices to maintain sample integrity and prevent cross-contamination:

• Use only PFAS-free materials when handling this product (recommended: stainless steel, silicone, high-density polyethylene)
• Avoid contact with potential PFAS sources including PTFE materials, waterproof clothing, food packaging, and certain personal care products
• Wear nitrile gloves and wash hands thoroughly before handling Implement appropriate field and laboratory blanks to verify absence of contamination
• Follow all method-specific quality control requirements for sampling, preservation, and analysis
