Thermal Desorption System and Accessories
Accessory Equipment
- GC Cryo-Trap -
The GC Cryo-Trap is used to cryo-focus volatiles at the front
of the GC column in a narrow band for subsequent heating and release.
Two models are available (CO2 and Liquid Nitrogen). The GC Cryo-Trap
is recommended for optimum results for the trapping of the lower
molecular weight volatiles.
- Thermal Desorption Conditioning System -
Used to bake out and condition desorption tubes and needle transfer
lines at high temperature with gas flow. Assures that no contamination
originates from your desorption tubes and needles. A 6 Tube Conditioning Oven
and a 24 Tube Conditioning Oven are
available.
- Sample Collection System - Used
to purge volatiles off 1 to 20 gram size solid samples onto adsorbent
resin traps for subsequent analysis via the thermal desorption
system. Used for the analysis of high water content solid samples
or when very low detection levels of volatiles is required.
- SIS Purge and Trap System - Used to
Purge Volatiles from liquid and solid samples onto adsorbent resin
traps. This low cost system is ideal for volatiles in beverages,
water and other samples requiring a sample between 1.o ml and
25 ml to be used.
- Wheaton Purge and Trap System -
Similar to the above but two size vessels are available for larger
samples (100 ml and 1.0 liter). Used when lower levels of analysis
are required and for the analysis of plant and flower material.
- Air Sampling Pump - A small, field
portable personal sampling pump for the collection of volatiles
from air samples onto adsorbent resin traps. This pump can handle
the backpressure needed for packed thermal desorption tubes and
can be set to accurately and reproducibility pump samples at flow
rates from 5 to 200 ml per minute.
- Thermal Desorption Sample Loader -
Used to inject liquid samples or internal standards in solution
onto the adsorbent resin trap. Assures total delivery of the sample
to the adsorbent resin without any loss due to evaporation.
- Gillibrator Air Flow Calibration System -
A primary air flow calibration system to calibrate sysems for
both positive and negative flows.
Accessories and Supplies

a double seal consisting of a graphite seal followed by a graphitized
vespel seal.
- Desorption Tube Needles - We recommend
the side port needle transfer lines to eliminate septum coring.
- Desorption System Fittings - A
wide selection of fittings for adapting thermal desorption tubes
to other equipment.
- SIS Purge and Trap System - Used to
Purge Volatiles from liquid and solid samples onto adsorbent resin
traps. This low cost system is ideal for volatiles in beverages,
water and other samples requiring a sample between 1.o ml and
25 ml to be used.
- Purge and Trap System Accessories - Glass Purging Vials,
purging needles and heating mantels for use with the Purge and
Trap System.
- Injection Port Liners - These low
dead volume liners provide for better heat transfer to the thermal
desorption needle and therefore assure better delivery of the
higher molecular weight compounds to the GC.
- Tenax TA Poster - The breakthrough
volumes for 200 organic analytes at temperatures from 0 degrees
to 300 degrees are listed for easy reference.
