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。

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.

预穿孔薄膜卷

对于分析人员而言，也可以选择预先穿孔3英寸长的薄膜卷，而不是连续卷，并且希望方便地分配预切割部分。只需根据需要从散装纸卷上的穿孔处拆下三个平方英寸的部分。每卷长300英尺，宽3英寸。单个预穿孔辊用于制备1200个样品，每个样品3英寸。

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，可提供较高的透光率百分比，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。

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

在SpectroMembrane®载架中，聚丙烯薄膜的厚度为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。
