A hydraulic press is used to consolidate sample materials into a flattened disc or pellet of consistent flatness and density. This is ideal for x-ray fluorescence (XRF) analysis which provides both quantitative and qualitative measurements of a sample’s elemental composition based on its subvisible excitation wavelengths. Matrix effects from surface variations and localized heterogeneities can alter a sample’s emission spectra, impacting net spectral measurements and impairing the accuracy of XRF spectrometry results.

Compacting samples using a hydraulic press enables analysts to perform spectral measurements on an ideal surface that is as close to a homogeneous representation of the bulk material as possible.

In this blog post, we will explore the working principle of...

Platinum (Pt) foils, ribbons, and sheets are essential intermediary goods used to fabricate a broad range of end-products. Despite the scarcity of this inert metal, it has been used ubiquitously in scientific equipment manufacturing for almost two centuries. High-temperature crucibles manufactured from pure platinum and various platinum alloys have become fundamental components in chemical research facilities around the world. These platinum products are essential for some of the highest sensitivity processing applications on the planet, including x-ray fluorescence (XRF) and inductively-coupled plasma (ICP) analysis.

Semi-finished platinum products boast far-flung product manufacturing capacities. This is due to the outstanding mechanical properties of platinum and its good affi...
