The new AutoDesorb System is the automated version of the
patented SIS "Short Path Thermal Desorption System". It is
designed for the automatic and unattended pickup, injection and
thermal extraction (thermal desorption) of volatile and semi-
volatile organics from solid, liquid and gas samples for analysis by
GC and GC/MS.
The AutoDesorb System consists of the AutoDesorb Tower
(which contains the sample analysis hardware), an Electronics
Console (which contains a microprocessor and power supplies)
and a PC Windows Software Package.
The system is operated and controlled by a PC Windows
based software package which operates within the Agilent
Technologies ChemStation software on the Agilent 6890 GC or
Agilent 5973/5975 GC/MS. It also works with the Agilent 5890
series GC (also Agilent 5971, 5972 & 5973 MSD) operating with
the latest version of ChemStation under Windows 95, NT or XP.
This provides a seamless integration of the Agilent GC or MSD
with the SIS AutoDesorb System. The AutoDesorb is also fully
integrated to operate with the Thermo TRACE GC operating under
the Xcalibur
TM
Software
The AutoDesorb Tower sits over the GC injection port, where
it is utilized for the direct desorption of both volatile and semi-
volatile samples into the GC injection port and column. Due to its
"short path" of sample flow, this system overcomes the limitations
of other desorption systems by eliminating transfer lines (which
are easily contaminated by samples) and by providing the
optimum delivery (and therefore maximum sensitivity) of samples
to the GC injector via the shortest path possible, i.e. direct
injection into the GC.
The desorption tube with sample for analysis is fitted with a
desorption tube needle and attached to a connecting tube. Each
connecting tube is sealed at the top with a spring loaded ball seal
to prevent sample contamination. A Carousel permits 12 samples
to be loaded for the unattended analysis of samples. When
signaled by the PC from the GC software, the AutoDesorb system
automatically locates and loads the sample, and then using the
prescribed desorption method, injects and desorbs the sample
into the GC. Samples can be run in any sequence using any pre-
viously saved method as specified by the Agilent ChemStation or
Xcalibur GC software.
