Description:
The SIS TD-5 is a “short path” thermal desorption system. It provides unattended thermal extraction (thermal desorption) and injection of volatile and semi-volatile organics from solid, liquid and gas samples into a gas chromatograph (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 desorbs 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 contains 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 cryogenically cools and rapidly heats the GC column head for improved chromatographic resolution.

The Short Path Thermal Desorption System provides several unique advantages over other desorption systems:
- It enables the sample, which is trapped on an adsorbent media contained in a Silco Coated SS (desorption tube), to be subjected to rapid heating.
- The desorbed component can be easily and efficiently transferred into the injection port of the gas chromatograph from a glass lined stainless steel sample tube and its associated injection needle. This provides for a short transfer path for the sample in an inert environment to minimize the degradation of labile sample components which often decompose upon contact with the hot catalytic metal wall surfaces of the transfer path of other systems.
- Third, each sample has its own individual adsorbent trap tube and needle to eliminate the possibility of cross-contamination from sample to sample, thus preventing any “memory effect” due to overloading of the sample in the Silco Coated desorption tube or due to residues from previous samples.
