Full support from collections to analyses. Collectors
are available for sampling solids, liquids, and gases.
 Feature
All collections are operated through steps consisting
of concentration and desorption to GC-MS with the primary
adsorption tube (PAT).
The industry's largest capacity quartz sample tube enables
various methods of analysis as follows:
♦ For gases, such as indoor or outdoor atmosphere, contaminants
are trapped in the PAT (primary adsorption tube) which is
packed with an adsorbent, i.e. Tenax. The PAT is then placed
in the JTD-505 II Purge & Trap and the VOC is desorbed
and cryofocused in the SAT (secondary adsorption tube) which
sends the contaminants into the GC/GC-MS. PATs are available
packed with the following adsorbents:
- Tenax GR 2.5 g
- Tenax TA 1.3 g
♦ For solids, such as, small electrical parts or polymeric
material are placed in the empty PAT which has an internal
volume of 10 ml, inner diameter of 12 mm and 50 mm high. Since
the PAT is already installed in the JTD-505 II, external outgas
collectors are not needed.
