This website describes the revolutionary capabilities of the new Model 3200/3250 Thermal
Desorption (Texas2Step™) system available from Microanalytics, the industry leader in
systems and software dealing with aroma and malodor analysis by GC/MS and
GC/MS-Olfactometry.
As of 2009, the Model 3200 thermal desorption system has
been superseded by the new Model 3250. With a simpler, more robust
pneumatics design, the 3250 offers the user:
-
Simpler and more inert carrier/desorption gas
flow path.
-
Simpler change-over from thermal desorption mode to liquid injection
(10 minutes)
-
Easier installation and
maintenance.
-
Innovative flow path allows removal of the desorption tube after
desorption cycle is complete. This reduces carryover, and
introduction of residual materials into the inlet. An "inlet
backflush" is initiated at this point to sweep the inlet area of any
contamination.
-
New inlet adapter, tray adapter and
purge point design for better tube handling.
-
New tube design to allow for easier
and more reproducible packing.
-
More cost effective alternative to the Gerstel
TDU for desorption of the SBSE-Twister™
(Stir Bar Sorptive Extraction).
Introduction
The Model 3250 is adaptable to any standard Agilent Model 6890/7890 GC.
It utilizes the base plate of a G1552A/G3452A split/splitless inlet with EPC;
which can be an existing injector or added as a new injector to the front or rear inlet
position of an existing instrument.
The name Texas2Step is derived from the fact that this system has the
optional ability to sample as well as desorb the trapped sample during a
completely
automated process. No other commercially available thermal
desorption system for GC has this blend of unique abilities.
Features and Benefits
The Model 3200/3250 systems offers the user a number of unique features not
found in other TD systems:
-
Automated Sampling and Desorption/Injection
processes.
-
Direct desorption into the column, no cryo-coolant
or expensive PTV inlet necessary.
-
Adaptable to a standard Agilent Technologies split/splitless
inlet
(G1552A/G3452A).
-
Quick change from thermal desorption mode to standard
liquid injection mode.
-
Robust stainless steel construction (inlet and
sample tubes) eliminates costly breakage.
-
Proprietary passivation techniques offers better
than glass inertness and prevents sample degradation.
-
Pre-purge mode removes residual air/oxygen from tube
before desorption.
-
Robotically controlled with the industry standard
CTC/LEAP Technologies CombiPAL or DI.PAL autosampler systems.
