CDS Analytical Thermal Desorption Systems

CDS applications

• The CDS 9300 Thermal Desorption System is the base model for single tube desorption featuring a hand-held controller for system maintenance and direct communication.  
  With the highest programmable valve temperature on the market (350°C),  the 9300 can venture into applications where other systems cannot perform, including VOCs, sVOCs, polar and nonpolar compounds.
• The CDS 9305 Thermal Desorption System adds a Mass Flow Controller (MFC) for near-real time sampling. An optional heated sampling line is available to collect air samples.  
• The CDS 9350 Thermal Desorption System is designed for continuous real time air monitoring with a dual thermal desorption tube setup. An optional heated sampling line is available.  
• The CDS 7550 AutoSampler is capable of 3D positioning within 1 mm, and thanks to its unique user settable calibration, it could handle any standard 3.5" Thermal Desorption tube. The Internal Standard module and Sample Saver module are optional.  
• The CDS 7550S AutoSampler is a stand-alone 72 position Thermal Desorption Autosampler for Thermal Desorption - Gas Chromatography - Mass Spectrometry (TD-GC-MS). The 7550S adopts two focus modes as Pre-desorb\Pre-heat function for high humidity sample, and optional Peltier module for lighter compounds, to improve the resolution of early eluting peaks.
