Passive Air Sampling Kits—Integrated
• Provide accurate integrated sampling without a sampling pump.
• Siltek® treated components ensure accurate sampling of active components.
• Excellent for sampling times from 0.5 hour to 125 hours.
Restek’s passive air sampling kit incorporates all the hardware necessary to collect air
samples, and is easy to assemble for field sampling.* The improved filter design greatly
reduces the number of potential leak sites.
The passive air sampling kit is available in seven sampling flow ranges, and in stainless
steel or Siltek® treated finish. The stainless steel kit is ideal to partner with the Restek
TO-Can® air sampling canister for TO-14A and TO-15 methods. Use the Siltek® treat-
ed version with the Restek SilcoCan® air sampling canister when collecting low-level
volatile sulfur compounds, or other active compounds.
*Air sampling canisters sold separately. See pages 410-411.

1. Veriflo® SC423XL flow
controller
This flow controller is the
heart of the sampling train. It
is a high-quality device
designed to maintain a
constant mass flow as the
pressure changes from -30"
Hg to 7" Hg (we recommend
you stop sampling at or
before 7" Hg of vacuum). All
wetted parts of the flow con-
troller can be Siltek® treated.

includes a stainless steel nut
on the inlet end, to prevent
water droplets from accumu-
lating at the edge of the
tubing, where they could be
pulled into the sampling
train.
4. 2-micron frit filter and
washer
Located prior to the critical
orifice to prevent airborne
particles from clogging the
critical orifice. Replaceable.
Available in stainless steel, or
Siltek® treated for optimum
inertness.
5. Interchangeable critical
orifice
An interchangeable ruby
critical orifice allows you to
control the flow with very high
precision.
