Passive Air Sampling Kits—Soil Gas
This unique grab sampler is specifically designed for soil gas sampling by allowing the
connection of tubing coming from the soil gas sample port. The innovative design min-
imizes connections and leaks and houses a critical orifice in the tee fitting. It also incor-
porates a vacuum gauge and 2 µm frit filter.
Assembled sampler includes:
• Stainless steel tee with orifice.
• 1

" vacuum gauge (-30" Hg to 0" Hg).
• 2 µm frit filter for insertion into
1

" compression sample inlet.
•

" port connector to canister valve.
The
1
/

" compression inlet and outlet allows easy connection to the canister valve and
also to the tubing from the sample port. Several orifice sizes provide sampling times
from 20 min. to 10 hours on a 6 L canister. Individual replacement parts are available,
providing a cost-effective alternative to replacing the entire sampler.
