XRF Technology In The Field - XRF Technology For Non-Scientists

Mar 21, 2022 | Thermo Fisher Scientific

X-ray fluorescence (XRF): a non-destructive analytical technique used to determine the chemical composition of materials XRF occurs when a fluorescent (or secondary) X-ray is emitted from a sample that is being excited by a primary X-ray source. Because this fluorescence is unique to the elemental composition of the sample, XRF is an excellent technology for qualitative and quantitative analysis of the material composition. XRF spectrometry has a broad range of applications in industry, which we will discuss later in this ebook....

Fundamentals of Capillary Ion Chromatography

Apr 29, 2021 | Peter Bodsky and Frank Hoefler

In this work, we highlight the fundamental differences between conventional IC (4 mm and 2 mm) and Capillary Ion Chromatography....

Column Properties That Make An Impact On Ion Chromatography

Apr 29, 2021 | Carl Fisher and John Guajardo

For the separation of ionic species, ion chromatography (IC), a type of liquid chromatography, is the method of choice. The most critical component of this technique is the separation column, which is selected based on factors that include the specific analytes of interest, the sample type and the required detection levels. This article outlines the column parameters that impact the separation of charged species in solution using ion-exchange chromatography and the developments that have continued to redefine what is possible with an IC system....
