Features
Analytical quality
-
High sensitivity thermal desorption and direct thermal
extraction of solid, liquid, and gas samples
-
No memory effects each sample has its own independent
and "short" flow path from sample to GC, eliminating transfer
lines as a source of contamination
-
Stainless steel sample tubes (glass-lined GLT 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
TM
accessory).
Functions/Convenience
-
Mounts overtop most GC injection ports--easily removable
and transferable.
-
Automatic injection and desorption of sample into GC
(pneumatic driven injector).
-
NEW
- Windows-based software for control and monitoring
of the system
-

S.I.S. TD-5
T
he new 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 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 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 con-
tains 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 cryogenical-
ly cools and rapidly heats the GC column head for improved chro-
matographic resolution.
