Using OSS ClearSamplerdiscs, identify an unknown material that is present in any facility. Ensure product quality is meeting normal standards or whether an unknown material may be present or possibly leaking from a package, exposing employees to undue risk.   Test an individual suspected of being exposed to drugs like fentanyl, or worse, to protect healthcare providers and first responders.

These ClearSampler discs are constructed of materials that do not interfere with the FTIR, ATR or Raman instruments that are used to determine the identity of the unknown material. OSS ClearSampler discs are designed to be used with any and all testing equipment.
