Sampling Bags from GL Sciences
Sampling bags are easiest to use for gas sampling at the measurements of the atmosphere, exhaust gas, and the working environment, etc.
It is an excellent method because it does not require any extraction with the solvent, or any sample preparation such as desorption
by heating when sample injection into the gas chromatograph. However, adsorption and penetration of a target compound are caused by
compound in the sample gas or material of the sampling bag, and there is a possibility that the composition of the sample gas may change.
Therefore, it is necessary to examine the material of the sampling bag is suitable for such a sample.
The sample bags are available in different sizes and materials like:
