SpectroCertified® XRF Sample Cup Quality
Chemplex XRF Sample Cups are fabricated from a proprietary high-density polyethylene thermoplastic specially formulated for this application. The material is characterized with:
- Compliant with the European Council Directive 2002/95/EC, RoHS, Restriction of Hazardous Substances.
- Consistent opacity without the addition of potentially contaminating “whitening” ingredients
- Lubricity to facilitate and ensure the smooth and firm attachment of thin-film sample support windows
- Physical characteristics for performance and resistance to thermal and irradiation exposure degradation
- Chemical resistance from contact with incalculable sample material substances
- Reportedly low and reproducible unavoidable trace impurity analytes
Typical Characteristics of Chemplex XRF Sample Cups
| Typical Trace Element Impurities, PPM | Melting Point, °C (°F) | Softening Point, °C (°F) |
|---|---|---|
| Ca, Mg, Ti, Al, P, Zn | 130 (266) | 123 (253) |
The extraordinary attention given to a special thermoplastic formulation and maintaining consistency of its physical and chemical properties is costlier than conventionally available plastics intended for general-purpose use. Chemplex XRF Sample Cups are unmatched in material composition and properties for their intended XRF scientific applications.
