(Cat. No. 690-302) and locate at appropriate
height.
b. Outdoors: Clip sampler(s) inside shelter
(open on two ends and bo om to allow air
to fl ow freely). Hang shelter securely at the
appropriate height.
Ensure diffusion holes in sampler are not
obstructed in any way.
2. Start sampling: Slide sampler cover to open
position (diff usion holes visible). Write sample
start time on pouch label.
3. Stop sampling: Slide sampler cover to closed
position (arrow and SKC visible). Write sample
stop time on pouch label.
Important: Measure and record ambient temperature
and atmospheric pressure. Include in information sent
to the laboratory.
4. a. Place sampler in its resealable pouch
immediately after sampling.
Or
b. Remove plug from sample sorbent
compartment. Remove lid from sorbent vial
and place opening of sorbent vial over the
compartment access port. Transfer sorbent
