Gas Sampling Bags

Gas sampling bags are widely used as whole air sampling devices for monitoring gases in cabin, emission, workplace environments, indoor, etc. The gas sampling method by bags is ideal for many applications because of the easy introduction to GC or enrichment by concentration tubes. However, the results of analyses may vary depending on the material of the gas sampling bags, which is caused due to permeation or adsorption of gases. In addition, background delivered from the bag materials may disturb the determination of the target compounds. Therefore selecting the right gas sampling bag material is essential for successful analysis.

GL Sciences provides high quality gas sampling bags for your gas sampling requirements. Foremost among our offerings is our new “Smart Bag” series of gas sampling bags which were developed based on our many years of experience in fulfilling customers' demanding requirements worldwide. We also carry other lines of gas sampling bags made of materials for other requirements.
