For Light-sensitive Compounds Black Layered Tedlar and Clear Tedlar with Stainless Steel or Teflon Fittings Frequently used for collecting light-sensitive compounds black Tedlar sample bags eliminate the need for cumbersome outer containers to protect the sample. SKC black and clear layered Tedlar bags allow for the convenient protection of light-sensitive compounds, while maintaining the integrity of the samples with an inner clear Tedlar layer. Black Tedlar contains carbon black that can absorb some compounds to the bag. Laboratory test on standard black Tedlar bags showed degradation after 24 hours compared to equivalent test with clear Tedlar. Using the black and clear layered Tedlar bag eliminates this problem. The SKC black and clear layered Tedlar bags are available with either a single stainless steel or Teflon fitting.

About the NCASI Method

For Sampling reduced sulfur compounds, the National Council for Air and Stream Improvement (NCASI) evaluated Tedlar sample bags with a light blocking layer (NCASI Tech Bulletin 656). For this method, SKC recommends a black layered Tedlar bag with a Teflon fitting (240-08B) or a stainless steel fitting (233-08B). When sampling for hydrogen sulfide using a stainless steel fitting, there is the possibility of sample loss (less than 10 %) that does not occur when using a Teflon fitting.
