Analytical chemistry is built on the premise of acquiring information about the composition and structure of sample materials through rigorous testing. This may involve the application of mechanical loads or extremely high temperatures to monitor the way that matter reacts to specific stressors. Although, the method applied fundamentally depends upon the properties of interest. Assessing the chemical content and structure of materials, for instance, is typically carried out via spectroscopic methods like X-ray fluorescence (XRF).

What is Spectroscopy?

Spectroscopy refers to a diverse toolset used to analyze materials based on various emission spectra. In this context, emission spectra are defined as the signals emitted by molecules after they have interact...

Among the most sensitive techniques available to biomedical experts and life scientists today, inductively coupled plasma (ICP) spectrometry enables trace element analysis of a wide range of sample types. Using a high precision electromagnetic array with a plasma torch and an integrated spectro-analytical detector, ICP solutions can reliably determine numerous chemical elements present in a sample down to the trace and ultra-trace levels. This analytical prowess means there are myriad ICP applications, from construction materials screening to biomedical research.

Understanding ICP Solutions

Part of the reason why ICP applications are so varied comes down to the outstanding flexibility of the method itself. A typical ICP array can be coupled with a choice o...

When analyzing samples by x-ray florescence analysis the two most popular methods of sample preparation are by lithium tetraborate fusion and by hydraulic pressing.  In the first video of our Expert Series when show you how to prepare samples for XRF analysis using a hydraulic press.  This method involves the use of an aluminium cup, binding agent and die set.
