XRF Scientific is one of the world’s leading suppliers of platinum products and tools for analytical applications, with over 40 years’ experience in the development of x-ray fluorescence (XRF) flux production and decades of success in the manufacture of custom fusion machines designed for XRF and inductively-coupled plasma (ICP) processes.

Our experience in the field of analytical platinum supplies (APS) precedes the listing of XRF Scientific. Years of combined experience enabled us to draw upon tried-and-tested methods while resolving long-established problems associated with analytical laboratory products. We now provide an extensive range of both fusion and general platinum labware, platinum electrodes and anodes for electrochemical analysis, alongside a variety of precisi...

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...
