Choice of double open-ended Cell for pre-attaching thin-film sample support windows, top sample filling and use in inert helium flush or atmospheric pressure.

Re-sealable cap integrates an external overflow reservoir and offers the option for venting. With the re-sealable cap rotated in the open position, an evacuation passageway is established from within the Cell to the integrated overflow reservoir and sample chamber. By re-positioning the cap, the passageway is closed for storage and future referral.

One of two supplied “Snap-On Rings” allows Microporous Film attachment to the upper Cell neck for pressure equalization within the sample cup and sample chamber. Microporous Film is attached to the upper end of the Cell Neck with a ridge. Alternatively, a “Vented Sample Cup Cap,”1600 Series, may be similarly used to maintain pressure equalization.ndent” geometry for establishing taut and leak-resistant sample windows.

Slit-Vented “Snap-On” Sample Cup Caps are unlike traditional caps with vented holes. These innovative caps are specifically designed to form a series of circular physical barriers when attached to a 1500 Series XRF Sample Cup. The barriers are created by the inter-relationship between integrated ridges on the interior of the cap and the Cell Neck when assembled. This forms circular troughs representing passageways leading from the interior of the sample cup to the sample chamber. The barriers present complicated paths of travel for sample particles to reach the sample chamber. Slit-Venting is used instead of traditional holes in order to increase the volumetric quantity of air withdrawal with minimum disturbances to the powdered sample substance while maintaining taut thin-film sample window planes.

SpectroMembrane Thin-Film Sample Support Carrier Frames consist of a thin-film sample support substance attached to a frame that serves as a carrier. In affixing a thin-film substance to an XRF Sample Cup, the thin-film material is not directly handled and a contamination possibility is completely eliminated. Nearing or at the completion of attachment, the thin-film automatically detaches from the carrier frame leaving a taut wrinkle-free sample support window.

The upper portion of the Cell is formed with a recession that serves as an external overflow reservoir for collecting and retaining thermally sensitive liquid samples. An easily rupturable ThermoPlastic® seal is centrally located to form a passageway from within the sample cup directly to the external overflow reservoir. Pressure equalization is easily established and maintained for taut thin-film sample support sample planes.

Microporous Film is a gas permeable membrane that enables the analysis of non-volatile liquid and powdered sample substances in helium flushes or vacuum. Pressure differentials within the sample cup and sample chamber are equalized while maintaining a taut thin-film sample support plane. The Series 1500 XRF Sample Cups are designed for use with Microporous Film.

Most powdered sample substances are considered multi-phased or compositionally complex. They are comprised of individual particles or crystal phases frequently dissimilar in composition, density, hardness, configuration, size and distribution. Each particle tends to behave as a separate entity from its surrounding constituents. Chemplex^® grinding and pelletizing additives are formulated to aid in the grinding and pelletizing process by reducing particles to a uniform size and distribution forming a homogeneous sample blend for XRF analysis. Under pelletizing pressure, the powdered samples are transformed into "plasticized" pellets with smooth unblemished surfaces resistant to inadvertent chipping or flaking apart. Samples may be saved for future referral.

The SpectroPulverizer is the perfect companion to any portable XRF analyzer. It is a compact kit to enable in-field grinding and pelletizing to get immediate consistent quantitative results.
