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.
