Made in USA

Thin-Film Sample Support Windows are available in Continuous Rolls, Pre-Perforated Rolls and Pre-Cut Circles interleaved with lint-free tissue carriers, in addition to SpectroMembrane® Thin-Film Sample Support Window Carrier Frames.

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.

Pre-Perforated Thin-Film Rolls

Thin-film rolls pre-perforated at 3” lengths are also available for analysts with a preference to continuous rolls and would like the convenience of dispensing pre-cut sections. Simply detach three square inch sections from the bulk roll at the perforations as required. Each roll is 300’ in length by 3” wide. A single pre-perforated roll serves to prepare 1200 samples at 3 inch per sample.

More Information

IMPORTANT: The chemical resistances of thin-films contained in the following table are provided as a matter of informational purposes only. They are not intended to preclude actual testing and suitability of use and applications. The responsibility of acceptance, suitability, testing, evaluation and safety resides totally with the user. Chemplex® Industries, Inc. assumes no liability whatsoever in using any thin-film sample support window substances and assumes no liability whatsoever for any information, advertisement, inferences, reports or any other form of communication written or orally presented.

Prolene®

Prolene® thin-film is a two constituent element combination of carbon and hydrogen. The light carbon and hydrogen element constituents together with gauge thickness translate into mass attenuation coefficients providing high % Transmittance values, an advantage for investigating the less energetic (KeV) analyte spectral lines in low element concentrations. Prolene® represents a good general purpose thin-film for most chemical solution samples except for those consisting of ethers or aromatic and halogenated hydrocarbons. It also is characterized with a relatively high sample retention tensile strength for safely containing samples in their sample cups. Prolene® thin-film is available in 3.0 and 4.0µm gauges and in SpectroMembrane® Carrier Frames.

Polypropylene

Polypropylene thin-film is available in 6.0 and 12.0 µm in SpectroMembrane® Carrier Frames. The thin-film serves a dual purpose; it is noted for its high % Transmittance for the lighter elements in low to medium concentration ranges and exceptional transmittance for the heavier element spectral lines. Reportedly, the thicker 6.0 and 12.0µm gauges are more preferable for retaining some samples and applications that demand an extraordinary higher level of security against inadvertent thin-film rupture.

MYLAR®
At one time, Mylar® thin-film was the only substance used in the XRF spectrochemical field and supplied only in roll form. With the passage of time, Chemplex® introduced the expansion of the Mylar® product line to include additional gauges and all other forms of physical presentation such as pre-cut square sheets, pre-cut circles, perforated pre-cut squares in rolls and recently in SpectroMembrane® Carrier Frames. Mylar® is a relatively good thin-film substance for general purpose aqueous sample solution containment. It has an excellent sample retention tensile strength. It is not suitable for containing aliphatic alcohols, alkalies, esters, aromatic hydrocarbons and keytones.

IMPORTANT: Some window materials may not be suitable for analyzing sulfur in diesel fuel, gasoline and other petroleum products containing aromatic hydrocarbons. ASTM D-6445-99 (Reapproved 2004) e1: "Samples of high aromatic content may dissolve polyester and polycarbonate films. In these cases, other materials besides these films may be used for X-ray windows, provided that they do not contain any elemental impurities. ASTM D 4294-08a: "Any film that resists attack by the sample, is free of sulfur, and is sufficiently X-ray transparent can be used. Film types can include polyester, polypropylene, and polycarbonate. However, samples of high aromatic content can dissolve polypropylene, polycarbonate and polyester."
