Main Features

72 Position Autosampler
CDS adopts a novel way to protect the TD tube by sealing in a reusable gas tight metal chamber, while waiting for the autosampler to pick up

Cryogen Free with Pre-Desorb and Pre-Heat
To improve the resolution of early eluting molecules, CDS uses a pre-desorb and pre-heat technique to mechanically confine analytes in a tiny space to improve focusing, which is more reliable than Peltier assisted focusing.

Stand-Alone Automsampler
The 7550S Thermal Desorption Autosampler has a built in focus trap and does not require a separate sample concentrator.

High Temperature Valve Oven at max 350°C
The high temperature oven (350°C) significantly extends the analyte range from VOCs to sVOCs.

Excellent TD Tube Compatibility
The autosampler can be configured to accommodate standard 1/4" x 3.5" TD tube from various manufacturers from its custom calibration interface

Powerful Windows Based Software
The software is Windows 10 compatible to give user full access to method editor and sequence table.

Built-in Leak Check
The automated leak check assures the system is air-tight before proceeding with the desorption of your sample.

Optical Sensor
The optical sensor detects the status of the TD tube on every step, both transporting to and from the heater oven.

Precision Robotic Arm
The robotic arm holds 1 mm X,Y,Z accuracy. The reliable gripping mechanism has the capability to handle both Pyrex glass and stainless steel tubes.
