The Importance of Spectrometer Calibration
A spectrometer is a term used for any instrument that is used to study, identify and analytically measure electromagnetic radiation that is emitted by a material, in order to identify the elemental composition of a material.
In X-ray fluorescence (XRF) spectrometry, samples are flooded with high-energy X-rays to find out what a material is composed of. This is carried out by measuring the fluorescent, or secondary, X-rays that are produced once they have interacted with the primary X-ray source.
What Is Spectrometer Calibration?
Although the XRF instruments hold many strengths, like any machine or instrument, they need regular maintenance in order to ensure an optimal performance. When a spectrometer is calibrated, it ensures the instrument is ‘se...
Fusion Furnaces and Their Applications
What are fusion furnaces and how are they used?
Fusion furnaces are machines designed to carry out sample preparation for analysis via x-ray fluorescence (XRF) spectroscopy and inductively-couple plasma (ICP) spectroscopy.
XRF and ICP spectroscopy are powerful techniques for chemical and elemental techniques, but each has very specific requirements for sample preparation. Fusion furnaces help to achieve high quality sample preparation through the controlled application of heat.
When preparing samples using fusion furnaces, the sample must first be finely ground to a powder. This powder is then mixed with a flux and introduced to the fusion furnace. Within the fusion furnace, the flux and sample mixture undergoes controlled heating in a crucible to high temperature...
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...
