Tubes and Caps
The ATD/TD uses industry standard, patented stainless steel tubes.
The stainless steel tubes are compatible with pumped and diffusive
air monitoring and can be ordered prepacked. Glass and glass-lined
tubes are also available for pumped monitoring. All tube types are
suitable for direct sampling of solids and liquids. PerkinElmer tubes
are manufactured to the tightest specifications to ensure trouble-free
operation and high-quality analysis results.
If you will be packing the tubes yourself, refer to Packing Sample
Tubes on page 284 for details.
The TD and ATD utilize a new capping system (Brass Storage caps
with ferrules P/N M041-3624 or PTFE Analysis cap P/N N620-
0119). ATD-400 type caps are not suitable for the TurboMatrix ATD.
[In the case of the TD, the tube will be decapped before it is inserted
into the instrument, so you can use existing ATD-400 caps or even
the Swagelok long term storage caps for your samples.]
To assemble the Brass Storage caps:
1. Place the PFA ferrule into the cap.
2. Screw the nut over the ferrule and onto the cap.

3. Do not over tighten the cap assembly.
4. Push the cap onto a tube. The cap should slide on easily
and should not fall off. If the cap is too loose, then
