Sharper peaks, better separations



CDS 9305
Near-real time sampling Thermal Desorption system.

The CDS 9305 Thermal Desorption system adds a Mass Flow Controller (MFC) for near-real time sampling. It features a hand-held controller for system maintenance and direct communication. With the highest programmable valve temperature on the market (350°C), the 9305 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 to collect air samples.
