Polyurethane Foam (PUF) Tubes
Polyurethane Foam Sorbent Tubes Polyurethane Foam (PUF) tubes are available in low volume (up to 24 hours) or high volume versions (for ambient air sampling)
Polyurethane Foam (PUF) tubes are available in low volume or high volume versions:
- The low volume PUF tubes (22 x 100 mm) are for measurements up to 24 hours at flow rates between 1 to 5 L/min.
- The high volume PUF tubes (65 x 125 mm) are designed for use with high volume samplers for ambient air sampling of organochlorine pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs).
To select a tube for a specific compound refer to the SKC Sampling Guides or use the SKC online Hazard Database
Low Volume Polyurethane Foam (PUF) Tubes
The Low Volume PUF Tubes:
- Meet the specifications of EPA TO-10A, EPA-IP-8, ASTM D4861.
- Can be used with personal sample pumps up to 5L/min
- Precleaned to meet method specifications
- Suitable for ambient, indoor or personal air sampling
- Sample up to 24 hours

High Volume Polyurethane Foam (PUF) Tubes
The PUF-only sorbent tubes meet ASTM D6209 and EPA IP-7, TO-4A and TO-13A, and are packed with precleaned PUF for low background. The PUF/XAD-2 combination tube meets EPA Method 600/8-80-038 specifications, and contains cleaned XAD-2 sorbent between two PUFs, which improves volatile component extraction during analysis.
