CDS Analytical 9305 Thermal Desorption Concentrator

Near‑Real‑Time Single‑Tube Sampling

Unlike traditional concentrators, the 9305 supports near‑real‑time, single‑tube sampling, making it ideal for:

• Continuous monitoring
• Time‑resolved VOC/SVOC studies
• Industrial emissions testing
• Rapid screening applications

This capability significantly enhances responsiveness and analytical throughput.

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.

Standard Vocarb Trap with Optional Tenax‑TA

The 9305 includes a standard 1/8" Vocarb trap, with optional 6 mm Tenax‑TA for expanded application flexibility.

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 13" × 11" × 18" and a weight of 19 kg, the 9305 is ideal for laboratories needing high‑performance TD‑GC/MS in a compact form factor.
