VOCs Adsorption Tube Combined Sampling Tube

Our VOCs combined sampling tubes are available in multiple sorbent bed configurations to accommodate different VOC target compound ranges and regulatory methods:

Single-Bed Configuration

• Tenax TA (200 mg): 2,6-diphenyl-p-phenylene oxide porous polymer; ideal for medium to high-boiling VOCs, benzene, and TVOC detection
• Tenax GR: Tenax/graphite composite; extended range to lower-boiling compounds
• Activated Carbon: Coconut shell activated carbon for broad-spectrum VOC capture

Dual-Bed Combination (Combination 1 & 2)

• Combination 1: Tenax GR (30 mm) + Carbopack B (25 mm) – suitable for a wide range of VOCs including aromatic hydrocarbons
• Combination 2: Carbopack B (30 mm) + Carboxen 1000 (10 mm) – optimized for both volatile and semi-volatile compounds

Triple-Bed Combination (Combination 3)

• Carbopack C (13 mm) + Carbopack B (25 mm) + Carboxen 1000 (13 mm) – comprehensive coverage from C3 to C16 compounds
