Key Considerations for XRF Pelletising
Determining a material’s elemental composition requires instruments’ sensitivity and stability to achieve accurate results. Previously, those two factors were the most common source of error in XRF analysis, but as technology has advanced, so have the XRF instruments, which has meant they are no longer the primary source of error in an XRF sample analysis. Instead, the most common problems are found in sample preparation techniques. This blog post will look at the key considerations when using XRF pelletising as a preparation method.
What is XRF Pelletising?
Pelletising is the process of making pressed pellets for XRF analysis. Pressed pellets are a...
What Makes Ammonium Iodide an Ideal Release Agent?
Ammonium iodide is the scientific name of the chemical compound NH₄I. It is used in colour dyes, explosives, photographic chemicals, medications and fire extinguishers, and is created by combining ammonia and hydroiodic acid.
How to Prepare Samples for XRF Analysis
XRF analysis is a comparative chemical analysis technique that can precisely identify and quantify myriad different elements in samples. These are identified under an X-ray by using flux. Flux shows the intensity of an X-ray beam, as well as the number of photons that appear and the per unit time from the X-ray. The measurement for flux is defined as photons per second, also known as p.p.s.

What Makes X-Ray Fluorescence Chemically-Specific?
X-ray fluorescence (XRF) is a non-invasive analytical method that is used to analyze the chemical and elemental composition of a wide range of materials. Traditionally, this method was used in Geology to determine the elemental makeup of rock, sediments, minerals and other earth samples, but its applications have now expanded.
What is X-Ray Fluorescence?
After a sample has been excited by a primary X-ray source, such as gamma or x-rays, it re...
