Needles for the AutoDesorb System

In the AutoDesorb™ System, the needle serves as the transfer

line for the introduction of the sample into the Gas Chromatograph.

This “short path” for sample transmission is the key advantage of

the Short Path Thermal Desorption technology which minimizes

sample decomposition, eliminates system contamination and pro-

vides for the maximum delivery of samples to the GC.

This 2 piece needle has been specifically designed for the

AutoDesorb system.

The new design will permit the sealing of the

needles and connecting tube to the desorption tube with just a

finger tight twist connection. Vespel™ seals (sold separately) are

used to make the leak tight seal. Double seals are not needed as

in TD3 and TD4 systems. The needles are of the side port design

to eliminate coring of the GC septa and are 35 mm long.

The nee-

dles are available in plain stainless steel and now also in Silco™

coated steel to eliminate any metal surface in contact with your

samples. These needles and seals can also be used in the Older

models of

the Thermal Desorption system (Models TD3 and TD-4)

as well as the most current version, TD5.

Seals for the AutoDesorb™ System

A single one-piece Vespel™ seal is used to make the leak tight

seal between the desorption tube and the needle as well as the

desorption tube and the connecting tube. These seals permit the

finger tight sealing of the desorption tube to the system.

Wrenches and tools are not required.

Seals can be used up to

450°C.

The double seals used in the TD5 are not used in the

AutoDesorb system.

Connecting Tubes and ‘O’ Rings for the

AutoDesorb System

The AutoDesorb™ System is shipped with 12 Connecting tubes,

however the user may wish to obtain additional spare connecting

tubes.

These connecting tubes are designed exclusively for the

AutoDesorb system and require both an ‘O’ Ring (purchased sep-

arately below) and a Vespel Seal (purchased separately as

listed above). Built into each connecting tube is a trap filter.

This

filter is packed with 40 milligrams of Carbotrap and is used as a

final filter to assure clean carrier gas is passed through you sam-

ple.

The trap filter can be cleaned by baking out in the tube con-

ditioning oven.
