Section 4 Consumables Thin Films for XRF Sample Cups XRF sample cup films allow liquids, powders and slurries to be analyzed by X-Ray Fluorescence. VHG Labs provides a range of special films of highest quality. For selection of the ideal film, consider the material’s transmission (especially important for "light elements"), purity, and physical strength. VHG Tips Only a limited sample available? When sample is limited, smaller sample cups can be used with accurate centering over the aperature made possible with a VHG Cup Positioning Guide. Why buy VHG’s pellet caps? • Firm support of samples & less susceptible to damage • Easy & convenient storage • Accommodated by all XRF spectrometers VHG’s pellet caps are made of thin wall aluminum with either straight side-walls or tapered side walls. They support and reinforce samples in cup presses and are useful for holding, transporting and storing powder samples. They have a painted exterior and eject simply from the mold assembly.
