CDS 7550S TD

A stand-alone 72 position Thermal Desorption Autosampler and sample concentrator

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

System description

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.

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.

Genetec is a member of the same family of companies as Kovalent. Both companies share the same set of values and are in many ways integrated with each other. The main difference between the two companies are their products. Kovalent is involved in system solutions including instrumentation and Genetec is mainly working with consumables. The focus of Genetec is chromatography accessories. You are welcome to visit their state of the art web shop:
