volatiles and semi-volatiles by GC and GC/MS.
NEW TD-5 system:
The TD-5 (the successor to the TD-4) is like the TD-4 but is controlled
by software on the PC and has a few minor hardware changes (e.g. larger
heaters).
Summary: The SIS TD-5 Short Path Thermal Desorption System
thermally extracts volatile and semi-volatile organics from solid,
liquid and gas samples for analysis by GC and GC/MS. It consists of a
Thermal Desorption Unit (Figure 1 - right) and an Electronics Control
Unit, which interfaces to Windows-based control software running on
the PC (Figure 2). The Thermal Desorption Unit sits directly on top of
the GC injection port of most GCs, where it introduces extracted
volatile and semi-volatile directly into the GC injection port and
column. Due to its "short path" of sample flow, this new
system overcomes the shortcomings of previous desorption systems by
eliminating transfer lines, which are easily contaminated by samples,
and by providing the optimum shortest path delivery (and therefore
maximum sensitivity) of samples to the GC injector, i.e. direct
injection into the GC, like using a GC injection syringe. The
Electronic Control Unit permits automated
operation including automatic injection, timed desorption, temperature
ramp of heater blocks, control of GC Cryo-Trap Accessory, and remote
starting of GC's, mass spectrometers, and recorders.

Major Features
- High sensitivity Thermal Desorption and Direct Thermal Extraction
System
- No memory effects - individual flow path for each sample preventing
contamination of transfer lines.
- Short Path from sample to GC
- Eliminate tedious sample cleanup by other techniques such
as solvent extraction
- Mounts overtop GC injection port, easily removable and transferable
- Automatic injection of sample into GC via pneumatic driven
injector
- Desorb samples at temperatures from up to 400 degrees C either
isothermal or temperature program at up to 100 degrees C/min.
- Glass lined stainless steel (GLT) sample tubes are both inert
to samples and strong for sample handling and transporting
- Windows-based control software. Optionally integrated into
Agilent ChemStation.
