CDS Analytical 9350 Thermal Desorption Concentrator

Continuous Dual‑Tube Sampling

The 9350 supports continuous, uninterrupted sampling using a dual‑tube configuration, making it ideal for:

• Real‑time emissions monitoring
• Industrial hygiene and workplace exposure studies
• Time‑resolved VOC/SVOC profiling
• Continuous environmental monitoring stations

This capability dramatically increases throughput and responsiveness.

High‑Temperature Desorption & Heated Pathway

The system features:

• Sample desorb temperature up to 400°C
• Focus desorb temperature up to 400°C
• Valve oven up to 350°C
• Heated transfer line up to 350°C

These high‑temperature capabilities ensure complete analyte recovery and minimal carryover.

Low‑Thermal‑Mass Vocarb Trap

The 9350 includes a standard 1/8" low‑thermal‑mass Vocarb trap, providing rapid heating, fast desorption, and excellent retention characteristics for VOCs and SVOCs.

No Cryogen Required

The system operates without cryogenic cooling, using standard pre‑desorb technology to maintain performance while reducing operating costs and complexity.

Compact & Efficient

With a footprint of 16" × 11" × 18" and a weight of 21 kg, the 9350 is ideal for laboratories needing high‑performance TD‑GC/MS in a compact form factor.
