SpectroFilm® offers the analyst a practical means to protect the x-ray tube and detector windows and related electronics from exposure to accidental sample material spillage. This is easily accomplished by affixing a self-sticking SpectroFilm® Safety Secondary Window between the stage separating the lower electronics compartment and upper sample chamber. A SpectroFilm® Self-Sticking Safety Secondary Window consists of a thin-film substance pre-affixed to a blue paper frame with a central aperture and an adhesive backing on the obverse side. Adhesive is protected with a removable release paper to expose the adhesive in readiness for attachment covering the opening in the platform intended to maintain separation between the sample holder and electronics chambers. Sample spillages are collected on the thin-film substance.

SpectroFilm®为分析人员提供了一种实用的手段，可以保护X射线管和检测器窗口以及相关的电子设备，使其免受意外样品材料泄漏的影响。通过在分隔下部电子装置隔室和上部样品室的载物台之间固定一个自粘式SpectroFilm®Safety Secondary Window，可以轻松实现此目的。SpectroFilm®自粘安全辅助窗口由预先粘贴到蓝纸框架上的薄膜物质组成，该蓝纸框架的中央有孔，正面上有背胶。用可移动的离型纸保护粘合剂，以使粘合剂易于暴露，以准备覆盖平台上的开口，以保持样品架和电子设备腔室之间的分离。样本溢出物收集在薄膜物质上。

SpectroFilm® is available in several different thin-film substances that offer a broad range of chemical resistance to sample spillages: Mylar®, Prolene® and especially Etnom®, which is noted for its exceptional resistance to both aliphatic and aromatic hydrocarbons. SpectroFilm® Safety Film is available in three similar thin-film gauges of similar percent transmittance values and tensile sample retention strengths.

可用的薄膜材料

Prepare the location where the SpectroFilm® is to be applied by cleaning and removing any residual oil or particles to provide a good bonding surface. Remove the release paper to expose the adhesive layer surface. Center the SpectroFilm® with the adhesive surface faced down directly over the aperture in the platform separating the sample holder and electronics compartments. Firmly press down the paper frame edges to ensure a complete and effective protective thin-film shield. Replace the SpectroFilm® Safety Secondary Film periodically to avoid the thin-film from becoming brittle after extended usage rendering it potentially ineffective. Thoroughly absorb, clean and dry any residual spillages and the surface separating the platform prior to re-applying a new SpectroFilm® Safety Film.

易于使用

NOTE: For effective seals the platform must be thoroughly cleaned and free of any oily substances, residual particles and other materials that may impair adhesion of the SpectroFilm®.

注：对于有效的密封件的平台必须彻底清洁和不含任何油性物质，残留颗粒和其他材料可能损害SpectroFilm的附着®。

For ease of identification, the obverse side of the SpectroFilm® is dark blue and the reverse side is lighter in color attributed to the translucence of the white release paper. SpectroFilm® is available with square or round paper frames of user choice. Removal of the release paper exposes the adhesive to secure the SpectroFilm® Safety Film in position.

为了便于识别，所述SpectroFilm的正面®是深蓝色和背面的颜色归因于白色释放纸的半透明打火机。SpectroFilm ®可与用户选择的方形或圆形纸制相框。离型纸的去除暴露出粘合剂固定SpectroFilm ®安全膜的位置。

SpectroFilm® can be made with virtually any thin-film material and thickness that is availale for the SpectroMembrane® product line. Additonally there are many other combination of sizes that can be made with our in-house equipment, for example a film with a 14mm aperture can be made with a 60mm diameter. Please contact us for your specific requirements.

SpectroFilm ®可以与几乎任何薄膜材料和厚度是availale为SpectroMembrane制成®产品线。此外，我们的内部设备还可以制作许多其他尺寸的组合，例如，可以制作直径为60mm的孔径为14mm的胶片。

产品应用：

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.

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 that consist 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 ®薄膜是由碳和氢的两个构成元件的组合。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 ®表示用于大多数化学溶液样品除了那些由醚或芳族和卤化烃的良好的通用薄膜。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 ®薄膜是在3.0和4.0μm计和在SpectroMembrane® 可用载体框架。

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 is has an excellent sample retention tensile strength. It is not suitable for containing aliphatic alcohols, alkalies, esters, aromatic hydrocarbons and keytones.

MYLAR®

在同一时间，MYLAR®薄膜是在光谱化学XRF领域中使用的和只以卷的形式提供的唯一物质。随着时间的推移，Chemplex®引入的聚酯薄膜的膨胀产品线，包括附加的仪表和所有其他形式的物理呈现的诸如预切割正方形片材，预切圆的，穿孔的预切平方成卷和最近在SpectroMembrane ®载波帧。MYLAR®是通用的水性试样溶液容纳一个比较好的薄膜物质。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。
