Traps for Volatile Organic Sampling Trains (VOST)

Method 0031 calls for three sorbent tubes:

• One Anasorb 747 sorbent tube (SKC Sorbent tube 226-133)
• Two Tenax sorbent tubes (SKC Sorbent tube 226-134)

Because of their low background levels, these specified sorbents are useful for collecting low concentrations of VOCs.
