How to use gas sampling bag

Grab samples of airborne contaminants at part-per-billion (ppb) to part-per-million (ppm) levels can be easily and effectively collected using a gas sampling bag. In industrial and research applications, it is frequently used to test the indoor and outdoor air quality.

When the bags are used properly, a sample is collected that is representative of the environment or process medium from which it was taken. One fixed monitoring point must typically be used when using complex, expensive, real-time gas analysis techniques to establish concentration levels.

Sampling Pumps

The use of gas sampling bags is a common method for finding impurities in biogas or biomethane. For safe and effective biogas processing, this method calls for trustworthy analytical methodologies.

The right bag material must be chosen carefully in this process for air sampling bags. The resistance of various materials to attack by particular chemicals or chemical groups varies.

If the target gas and the bag material are incompatible, adsorption or permeation may take place and the sample may not be properly analyzed.

This is why it's crucial that a sample is properly obtained and delivered to a lab. For this, a suitable gas sampling pump must be used, as well as a sampling bag with an inflation valve.

Biomethane and biogas can be reliably analyzed by using the right pumps and sampling bags. To prevent the bags from over-inflating during the sampling period, the proper pumping pressure for the bags must not be greater than 0.25 psi (17.4 mbar).
