XRF Scientific: A Reference Material Manufacturer
As defined by the International Organization for Standardization (ISO), reference materials are “sufficiently homogeneous and stable with respect to one or more specified properties, which has been established to be fit for its intended use in a measurement process”.
Here we will outline the role of reference material manufacturers, what we produce, while outlining the difference between reference materials and certified reference materials.
What is a Reference Material Manufacturer?
A reference material manufacturer develops reference materials according to standards set out by the ISO.
The ISO published a guide on what standards reference material producers (RMPs) must adhere to if they are producing reference materials (non-ce...
The Working Principle of an XRF Spectrometer
An X-ray fluorescence (XRF) spectrometer is an X-ray instrument that is employed for the routine chemical analysis carried out on sediments, rocks, minerals and fluids. It is a relatively non-destructive technique that works on wavelength-dispersive spectroscopic principles. XRF instrumentation is generally used for bulk analyses of larger areas of minerals and materials.
The Key Principles of XRF
The technique used by XRF spectrometers is possible because of the behavior of the atoms when they interact with radiation. If material is excited via high-energy, short-wavelength radiation it may become ionized. If the energy is high enough it will have the capacity to dislodge an inner electron that has been tightly held. After this, the atom becomes unstable ...
Fusion Machine Suppliers Across the World
Every day, thousands of researchers worldwide entrust fusion machine suppliers with their sample preparation. Fusion machine suppliers play a vital role in ensuring that fusion machines are capable of quick, straightforward and – most importantly – consistent results. In this blog, we explore how fusion machines work, their benefits, and the different technologies that fusion machine suppliers use to prepare XRF and ICP analysis samples.
What is a fusion machine?
Fusion machines are used to prepare solid samples in “fused bead” or “fused disc” form for analysis via x-ray fluorescence (XRF) spectroscopy or inductively coupled plasma (ICP) spectroscopy.
Before fusion takes place, the sample must be ground into a fine powder. This powder is...
