Summaries

The CDS 9350 Thermal Desorption system is designed for continuous real time air monitoring with a dual thermal desorption tube setup. It features a hand-held controller for system maintenance and direct communication. With the highest programmable valve temperature on the market (350°C), the 9350 can venture into applications where other systems can not perform, including VOCs, sVOCs, polar and nonpolar compounds. The two stage trapping and desorption process with Pre-desorb and Pre-heat feature eliminate the need of any Peltier cooling or liquid cryogen to improve the resolution for early eluting molecules. An optional heated sampling line is available. 

Product Features
Versatile Configurations to Mainstream TD Tubes

The CDS 9300 families could be configured to adopt 6mm x 4.5" CDS TD tube, 10mm x 4.5" CDS TD tube, 1/4" x 3.5" PE and Markes TD tube, Tekmar 1/4" x 7" tube and VOST 16mm x 5" TD tube

Cryogen Free with Pre-Desorb and Pre-Heat

To improve the resolution of early eluting molecules, CDS uses pre-desorb and pre-heat technique to mechanically confine analytes in the focus tube until the desorption temperature is reached.

Hand-Held Plug-in Control Interface

This hand-held interface gives you easy access to the Thermal Desorption system without using a PC. This is an essential feature for mobile labs in field sampling and analysis.

High Temperature Valve Oven at max 350°C

The high temperature oven (350°C)  significantly extends the analyte range from VOCs to sVOCs.  

Built Tough with Easy Maintenance

The CDS 9300 is built tough on military standard. Routine maintenance only requires basic tools in accessing the components. 

Powerful Windows Based Software

The software is Windows 10 compatible to give user full access to method editor and sequence table.

Dual TD Tubes

The 9350's thermal desorption chamber supports dual TD tubes for continuous sampling when one of the TD tube is desorbing. 

Low Thermal Mass Trap

The 9350 features a standard 1/8" low thermal mass focus trap in its own desorption chamber for fast heating and cooling.

Optional Heated Sampling Line

This optional heated sampling line is handy when doing remote sampling.
