Features:

•

High sensitivity thermal desorption and direct thermal

extraction of solid, liquid, and gas samples

•

No memory effects – each sample has its own inde-

pendent and “short” flow path from sample to GC,

eliminating transfer lines as a source of contamination

•

Stainless steel sample tubes (or silco treated) are inert

to samples and strong for sample handling

and transporting.

•

Rapid cryogenic (CO2 or LN2) cooling and heating of

the GC column head for improved chromatographic

resolution (optional Cryo-Trap™ accessory).

•

Mounts overtop most GC injection ports—easily

removable and transferable.

•

Automatic injection and desorption of sample into GC

(pneumatic driven injector).

•

Windows-based software for control and monitoring

of the system.

•

Seamless integration into Agilent ChemStation™

and Thermo Fisher Scientific Xcalibur™

•

Optional - stand alone operation with other top

injecting GC’s

•

Desorption: temp range: 20° to 400°C, either

isothermal or temperature programmed.

Max heat

rate: 100°C/min.

•

Cryo-trap: min temp: -70°C (CO2) or -180°C (LN2).

Max temp: 400°C.

Max heat rate: 10°C/sec.

T

he new SIS TD-5 is a "short path" thermal desorption

system. It provides unattended thermal extraction (ther-

mal desorption) and injection of volatile and semi-volatile

organics from solid, liquid and gas samples into a gas chromato-

graph (GC). The system delivers samples into the GC along an

optimal “short path,” thereby eliminating

transfer lines and cross-

sample contamination issues found in previous systems.

A sample for analysis is introduced into a desorption tube, which

is then fitted with a needle and attached to the TD-5 Desorption

Unit. The Desorption Unit sits over the GC injection port, where,

upon signal from the PC software, it automatically injects and des-

orbs the sample into the GC injection port and column using the

temperatures and times prescribed in the desorption method.

The TD-5 System consists of the Desorption Unit (which con-

tains the sample analysis hardware), an Electronics Console (which

contains a microprocessor and power supply), and a Windows-

based Thermal Desorption software (which provides control and

monitoring of the system). This software can be fully integrated with

selected GC data systems (e.g. Agilent ChemStation), or it can

operate fully independently from the GC data system. Various

accessories are available such as the Cryo-Trap, which cryogeni-

cally cools and rapidly heats the GC column head for improved

chromatographic resolution.

Multi-sample version of our Thermal Desorption System is

also available. See pages C6 - C9 or visit www.sisweb.com
