A gas sampling bag made of a flexible synthetic polymer has extremely low background contaminants in its interior and is treated to minimize further contaminant intrusions from its coupling components. Methods of making the bag are described; the invention includes a sampling bag, with treated inlet fittings, holding a gas sample having controlled low background contamination from volatile organic compounds.
