CDS 7550s Autosampler

CDS 7550S
Stand-alone 72 position Thermal Desorption system

The CDS 7550S is a stand-alone 72 position Thermal Desorption Autosample which does not need a separate sample concentrator, like the 7550 model. Built on the 2nd generation autosampler platform, the CDS 7550S is capable of 3D positioning within 1 mm, and thanks to its unique custom calibration, it could handle 3.5" standard Thermal Desorption tube from any manufacturer. These features make CDS 7550 the most reliable Thermal Desorption autosampler available to the market. The 7550S adopts two focus modes as Pre-desorb and Pre-heat function for high humidity sample, and optional Peltier module for lighter compounds, to improve the resolution of early eluting peaks.
