Smart Bag Air Sample Collection Bags
Compare to Tedlar Sample Bags
Sampling bags are widely used as a handy sampling method for automobile interior materials/emissions, work environments, building materials and textiles.
Sampling bag method is an ideal method for the above mentioned applications as the sample gas can be directly injected to the gas chromatograph and convenient to collect samples using adsorbent products to enrich/concentrate the target compounds. However, the composition of the target compounds can be changed depending on the materials of the sampling bags, which is caused by the adsorption or permeation of the target compounds to the materials of the sampling bag. In addition, background peaks derived from sampling bag materials can interfere the target compounds’ peaks during GC/MS or LC/MS analysis. Therefore the "optimum" collection bag configuration is very much dependent on the application or method so as to maximize recovery of the compounds of interest and sensitivity of detection in downstream analysis.
GL Sciences is proud to introduce its “Smart Bag” series of air sample bags which offer advantages over Tedlar bags for several applications by reducing non-specific binding and increasing recovery of certain compounds.
In addition to supplying our sample collection Smart Bags (as well as Tedlar brand collection bags), GL Sciences also supplies GC columns, HPLC columns, and solid phase extraction (SPE) columns for analysis of many of the compounds collected for envinronmental or industrial hygeine analysis.
For example, GL Sciences'
