The CDS 7550S is a stand-alone 72 position Thermal Desorption Autosampler for Thermal Desorption - Gas Chromatography - Mass Spectrometry (TD-GC-MS) in the analytical lab. 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\Pre-heat function for high humidity sample, and optional Peltier module for lighter compounds, to improve the resolution of early eluting peaks.
