Thin Films for XRF Sample Cups

XRF sample cup films allow liquids, powders and slurries to be analyzed by X-Ray Fluorescence. VHG Labs provides a range of special films of highest quality. For selection of the ideal film, consider the material’s transmission (especially important for “light elements”), purity, and physical strength.

Kapton® (Polyimide)
Features high strength, high purity, chemical robustness, and withstands prolonged X-Ray irradiation.

Mylar®
Mylar (polyethylene-terephthalate) film is economical, strong and offers good chemical resistance. It is well suited for light element analysis (Note: may contain Ca, Fe, P, Sb, Zn).

Optilene-XF™
Highest grade, proprietary film featuring optimal transmission, purity, strength, chemical resistance, and thermal stability. Good for full range of XRF analytes, including light elements.

Polycarbonate
Features excellent X-Ray transmission characteristics and good chemical resistance.

Polypropylene
General purpose film with good transmission and chemical resistance (Note: may contain Al, Ca, Cu, Fe, P, Ti, Zn, Zr).
