Gas sample bags are a convenient and accurate means of gas and vapor samples in air. This is particularly true in areas where the concentration is above the detection limits of common analytical instruments.

Many chemical hazards can be effectively collected by sample bags. But, while the collection method is simple, the selection of the bag, fittings, and tubing is critical. Contact us today and we will help you find the specific bag to suit your needs.

Some tips for using Sampling Bags. When sampling for light-sensitive compounds, use black and clear layered Tedlar® bags. Use only Teflon® tubing and Teflon-lined septums for bag sampling, flush the bag thoroughly with purified air or nitrogen before using. Do not use bags to collect unstable or highly reactive compounds. Do not ship sample bags by air unless the cargo cabin is pressurized. Avoid filling the bag more than 80% of its maximum volume. At the end of the sampling period, turn the pump off and close the valve on the bag.
