Thin-Film Sample Support Windows are available in Pre-Cut Circles interleaved with lint-free tissue carriers.

薄膜样品支持窗口可在预切割圆中与无绒组织载体交错使用。

Features：

● Interleaved with lint-free tissue

   2.5" (63.0mm)

   3.5" (89.0mm)

特点

● 与无绒纸交错

● 2.5英寸（63.0mm）

● 3.5英寸（89.0mm）

The Precut Circle Thin-Film Sample Support Windows are pre-cut in circular shapes for easy assembly onto XRF sample cups. The Chemplex Precut Circle Thin-FIlm Sample Support windows are also are packaged in a box and interleaved with lint-free tissue carriers so the Thin-Film Sample Support Windows do not adhere to eachother.

Precut Circle薄膜样品支持窗口已预先切割成圆形，易于组装到XRF样品杯上。Chemplex Precut Circle薄膜样品支持窗口也包装在一个盒子中，并与无绒组织载体交错放置，因此，薄膜样品支持窗口不会相互粘附。

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.

所有薄膜的制造和存储均在环境可控的条件下进行，并立即单独包裹在透明塑料中，以保持原始完整性。这些额外的预防措施是必要的，以避免潜在地引入痕量污染物（可能影响X射线数据）的潜在可能性。

ETNOM®

Etnom® was the first thin-film substance to chemically resist attack by aliphatic and especially aromatic hydrocarbons and have the unique characteristic of contracting when exposed to petrochemical hydrocarbons. This unique characteristic allows the thin-film to remain taut when exposed to samples containing these hydrocarbons and maintain a consistent taut flat sample support window plane during the entire integration time of analysis. Etnom® is available in a variety of thicknesses ranging from 1.5 through 3.0μm; it is frequently used and ideally suitable for sulfur analysis in aliphatic and particularly aromatic hydrocarbons. 2.0, 2.5 and 3.0μm Etnom® thin-films are limited in availability only to SpectroMembrane® Carrier Frames

ETNOM®

Etnom®是第一种化学抵抗脂族（尤其是芳香族）烃侵蚀的薄膜物质，并具有独特的在暴露于石化烃时收缩的特性。这种独特的特性使薄膜在暴露于含有这些碳氢化合物的样品时仍能保持绷紧状态，并在整个分析过程中保持一致的绷紧的平坦样品支撑窗平面。Etnom®的厚度范围从1.5到3.0μm不等。它经常使用，理想地适用于脂肪族尤其是芳香族烃类中的硫分析。Etnom®2.0、2.5和3.0μm薄膜的可用性仅限于SpectroMembrane®承载框架

Zythene®

Zythene® thin-film is chemically resistant to petrochemicals and, unlike any other thin-film, is also capable to contract upon contact with aliphatic and aromatic hydrocarbons. This particular trait is responsible for establishing and maintaining taut sample support window planes during the entire integration time of analysis. Adding this unique quality to the unusually high sample retention tensile strength of Zythene®, samples are safely contained in their sample cups with a rare likelihood of rupture. Coincidentally, 6.0μm Zythene® exhibits a similar mass attenuation coefficient to 6.0μm Mylar®. This implies the % Transmittance of 6.0μm Zythene® and 6.0μm Mylar® is similar and the expectant element spectral-line intensities are also similar. However, this similarity does not negate the need for cursory calibration verification. 6.0μm Zythene® is limited in availability only to SpectroMembrane® Carrier Frames.

Zythene®
Zythene®薄膜对石化产品具有化学抗性，并且与任何其他薄膜不同，Zythene®薄膜在与脂族和芳族烃接触后也能收缩。这种特殊的特性负责在整个分析过程中建立和保持绷紧的样品支持窗平面。这种独特的品质为Zythene®异常高的样品保持拉伸强度增添了优势，样品安全地容纳在其样品杯中，极少发生破裂。巧合的是，6.0μmZythene®的质量衰减系数与6.0μmMylar®相似。这意味着6.0μmZythene®和6.0μmMylar®的透光率相似，并且预期元素光谱线强度也相似。但是，这种相似性并不能消除对粗略校准验证的需求。

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.

Prolene®

Prolene®薄膜是碳和氢的两个组成元素组合。轻质碳和氢元素成分与标称厚度一起转换为质量衰减系数，从而提供较高的％透光率值，这对于研究低元素浓度的低能（KeV）分析物光谱线而言具有优势。Prolene®是大多数化学溶液样品的良好通用薄膜，除了那些由醚或芳香族和卤代烃组成的样品。它还具有相对较高的样品保持拉伸强度，可将样品安全地容纳在样品杯中。Prolene®薄膜有3.0和4.0μm规格以及SpectroMembrane®托架。

Our 7.5μm Kapton® thin-film available from Chemplex® exhibits similar properties as the previous traditionally used type: 7.5μm gauge, high sample retention tensile strength, equivalent % Transmittance values of x-rays, chemical resistance and melting points. The difference between the other Kapton® films and the Chemplex® 7.5μm Kapton® thin-film is “it is not subject to the U.S. International Traffic in Arms Regulations (ITAR).” Reportedly, an unknown slight difference between the ITAR controlled and the new 7.5μm Kapton® thin-film may affect the reliance on previously established calibration data. Chemplex® suggests judiciously re-examining this issue for verification prior to implementing an analytical program.

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.

聚丙烯

SpectroMembrane®托架中的聚丙烯薄膜厚度为6.0和12.0 μm。薄膜有双重作用。在中低浓度范围内，它对较轻元素的透光率很高，而较重元素光谱线的透光率却很高。据报道，较厚的6.0和12.0μm厚度的量规更适用于保留一些样品和应用，这些样品和应用需要极高的安全性以防止薄膜意外破裂。

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.

MYLAR®

薄膜是XRF光谱化学领域中使用的唯一物质，并且仅以卷筒形式提供。随着时间的流逝，Chemplex®引入了Mylar®产品线的扩展，以包括其他量规和所有其他形式的物理表示形式，例如预切方形纸，预切圆，成卷的穿孔预切方形纸以及最近的产品。在SpectroMembrane®支架中。Mylar®是用于通用样品水溶液容纳的相对较好的薄膜物质。它具有出色的样品保持抗张强度。它不适用于包含脂族醇，碱，酯，芳烃和基调。
