SAMPLE HANDLING | AIR SAMPLING
Gas Sampling Bags
The model 1062 vacuum bag sampler
provides fast sampling with zero cross-
contamination. A vacuum created in
the box draws air into the sampling bag
without drawing it through the vacuum
pump first, as is the case with standard
air sampling pumps, thereby preventing
contamination of the sample. This bag
sampler can fill a 10 L bag in two min-
utes with an automatic shut-off switch, which stops the sample bag from overfilling.
The filling rate is adjusted with a vent rotometer valve. An external battery-recharging
port enables continuous operation with battery charger. In addition, the quick exhaust
valve allows for fast removal of the sampling bag. The sampler comes with a universal
power adaptor/charger, battery, instruction manual, and 1-year limited warranty.

General Guidelines for Bag Sampling
Follow these basic considerations for trouble-free air sampling using gas sampling bags.
Before Sampling
• Store unused bags in a clean environment, sealed in an outer bag to prevent adsorption of contaminants.
• Preclean bags before use by flushing with high-purity nitrogen.
• For validation, compounds must be stable at >80% for 72 hours.
• Leak rate must not exceed 0.1" Hg/min.
During Sampling
• Be sure the PTFE tubing used for bag connection is clean.
• Use a vacuum box sampler for direct bag filling in order to avoid contamination from a sampling pump.
• Typical flow rate is 3 L/min.
• Do not fill bags more than 80%.
After Sampling
• Bags are intended for a single use due to potential sample adsorption onto the bag film.
• Hold times are typically 48 hours unless validation study demonstrates longer stability.
• Protect samples from direct sunlight and store above 0 °C to prevent condensation.
• Transport in rigid, opaque container to prevent bag puncture; do not ship by air unless samples will be kept in a pressurized area.
