thin Mylar PET film used for XRF samples cup

3.5micron thick high purity Mylar Pet Film is transprent mylar Polyester Film with thin thickness used for the analysis of low Sulfur levels in road fuels. Consistently ensures the extremely low and constant background that is essential when working at low Sulfur levels (ppm). Provided in box with serrated edge for tearing to desired length.XRF thin polyester film as support sustance carrier attached to a frme in affixing a thin Clear Pet Film substance to an XRF samples cup ,The thin- Pet Material Film is not directly handled and a contamination possibility is completely eliminated. Nearing or at the completion of attachment, the thin-film automatically detaches from the carrier frame leaving a taut wrinkle-free sample support window#XRF sample film Polyester film thickness:1.9u,2.4u,3u,3.5u,4u,6u

In addition to the film possessing very small standard deviations in the point-to-point thickness values, it is also essentially free of the low level contaminants that can occur in films of any type at any time. However, there can be some impurity elements present in the low ppm range,

hence it would be good laboratory practice to always run a "blank" film control only to be on the safe side of all interpretations.
