Sampling
Allow pump to equilibrate after moving it from one temperature extreme
to another.
1. Replace the representative sample media used for
calibration with new, pre-weighed media (
see Media
Preparation and Impactor Preparation
).
2. Mount the bracket at the desired location and at breath-
ing zone height (6 feet or 2 meters) using wire ties or
other fasteners. Mount the impactor on the mounting
bracket by threading the clamp knob into the bo
tt
om of
the impactor.
3. Insert the screw on the rain cover into the screw hole in
top of the impactor inlet and rotate the cover until tight.
4. Turn on the pump and record sample start time, ambient
temperature, ambient pressure, and other pertinent data.
Sample start time and duration can be programmed
into the Leland Legacy Sample Pump in advance and
sampling may be started manually or automatically.
Record all necessary data before disconnecting the
pump from the ba
tt
ery and reconnecting to the new
ba
tt
ery.
5. After desired sample time has elapsed, turn o
ff
the pump and record the
sample stop time, total volume, ambient temperature, ambient pressure, and
other pertinent data.
6. Remove the rain cover, reinstate the calibration
train and media, and verify the
fl
ow rate (
see Cali-
bration
).
7. Reach inside the case and press quick-connect
release while pulling the tubing from the inlet.
Remove tubing from the impactor.
Technical Tidbits
•
The supplied rain cover should be used for all outdoor sampling.
•
Keep the Leland Legacy sample pump inside the Pelican case and the
case closed during sampling to protect the sample pump from weather.
