CDS Analytical 9300 Thermal Desorption Concentrator

Flexible, Programmable Purge & Trap Control

The 9300 offers fully programmable timing from 0 to 999.9 minutes, allowing precise control over purge, dry purge, desorb, and bake cycles. This flexibility supports a wide range of sample matrices and method requirements.

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 minimize carryover.

Standard Vocarb Trap with Optional Tenax‑TA

The 9300 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

Weighing only 17 kg, the 9300 is designed for laboratories needing a powerful concentrator in a compact footprint.
