The 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 7850, 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™ 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.
