The 232, 236, 252, and 262 Series sample bags feature a single polypropylene
fi
tt
ing
that is used for both
fi
lling the bag and removing the sample for analysis. The
fi
tt
ing
contains a syringe port with septum and a hose connection and acts as a valve to
open or close the hose connection.
Guidelines for Bag Sampling
1.
Ensure that the bag material and
fi
tt
ings are appropriate for the
compounds to be sampled.
2. Use only PTFE tubing to connect the sample bag to the pump to prevent
sample loss by adsorption on tubing walls.
3. Before using,
fl
ush the bag thoroughly with puri
fi
ed air or nitrogen.
4. Analyze the sample within 24 to 48 hours. Long-term storage of air-
contaminant mixtures in bags is not recommended.
5. Do not ship sample bags by air unless the cargo cabin is pressurized.
6. In
fl
ate bag properly
(see Proper Bag In
fl
ation for details)
.
7. Due to the physical properties of FlexFoil
®
bag material, minor crimps and
creases may appear on the bags during SKC manufacturing, quality testing,
and user handling. These marks only a
ff
ect the aesthetics of the bag and not
its performance. FlexFoil bags exhibiting minor crimps and creases are not
subject to replacement or refund as functionality is not a
ff
ected.
Notes and Cautions
• Maximum Operating Temperature —
Do not exceed these speci
fi
cations:
• 236 Series Bags:
140 F (60 C) due to the SamplePro
®
FlexFilm bag material
temperature
rating
• Do not use sample bags to sample compounds with boiling points > 249.8 F (121 C).
• SKC sample bags are designed for sampling air at atmospheric pressure only. A
tt
empting
to pressurize the bag can result in bag rupture and sample loss. Do not ship bag samples
by air freight in non-pressurized cargo cabin. Bags can burst under such conditions.
• All federal and state packaging and transporting regulations apply.
• SKC bag
fi
tt
ing valves are extremely durable but are not intended for use as handles
or hanging devices. This type of handling may damage the seal, causing leakage. This
is considered to be misuse and will void the SKC warranty.
• Failure to follow warnings and cautions voids any warranty.
• Sample bags are designed for single use only.
