Which device uses a Tedlar bag to sample gas and bring it to GAS ID for chemical name identification?

• A. MX908
• B. QRAE
• C. ToxiRAE
• D. MiniRAE 3000

Answer: (D)

Tedlar bag sampling is used when you need a preserved sample that can be sent to a dedicated identification instrument to determine the exact chemical name, not just the concentration. The GAS ID system performs that identification, so the workflow involves collecting a sample in a Tedlar bag and delivering it to GAS ID for name identification. Among the options, the MiniRAE 3000 is the one designed to support that bag-sampling workflow and interface with GAS ID, enabling chemical-name identification of the VOCs in the bag. The other devices are real-time detectors (multi-gas or single-gas toxic detectors) that provide on-site readings but aren’t used for bag-based chemical-name identification with GAS ID.
