The Precut Circle Thin-Film Sample Support Windows are pre-cut in circular shapes for easy assembly onto XRF sample cups. The Chemplex Precut Circle Thin-FIlm Sample Support windows are also are packaged in a box and interleaved with lint-free tissue carriers so the Thin-Film Sample Support Windows do not adhere to eachother.
Fabrication and storage of all thin-films is performed under environmentally controlled conditions and immediately individually shrink-wrapped in clear plastic to preserve the original integrity. These extra precautionary measures are necessary to avoid the potential possibility of inadvertently introducing trace levels of contaminates that may affect x-ray data.
