436 - XRF Thin-Film Sample Supports, Chemplex - Pre-Cut Circles - Pack of 500

Description

For retaining liquid, powdered, slurry or solid specimens in XRF Sample Cups for wavelength (WDXRF) and energy dispersive (EDXRF) spectrochemical analysis. Chemplex thin-film sample support substances are manufactured to very close tolerances (1 to 2% within a single package)Choose from Prolene, ultra-polyester, polypropylene, Mylar, polycarbonate or polyimide support materials based on their ability to safely retain specimen during preparation and analysis stages, permit maximum analyte-line transmittance, and provide statistically reproducible analytical data. Considerations for selecting an appropriate thin-film material include: resistance of material to degradation by the analyte, analyte concentration/wavelength, thin-film purity and thin-film thickness uniformity. Available in continuous rolls, precut squares and circles.
