ICP (Inductively Coupled Plasma) Spectroscopy is an analytical method used to detect and measure elements to analyze chemical samples. The process is based on the ionization of a sample by an extremely hot plasma, usually made from argon gas.

In an ICP spectroscopy unit, argon gas streaming through a torch apparatus is charged with an electromagnetic coil and lit with a Tesla unit that produces a quick discharge arc through the argon flow to trigger the ionization sequence. As soon as the plasma is “lit,” the ICP spectroscopy unit is switched off the Tesla device.

The electrons accelerated by the torch collide with argon atoms, and occasionally a collision leads to an argon atom shedding one of its electrons. Released electrons are then accelerated by the elect...

X-ray fluorescence (XRF) spectroscopy is a non-destructive analytical technique that studies the fluorescent x-rays that are emitted from a material. It is often used for chemical or elemental analysis to discover the composition of a material. This blog post will outline some of the applications that benefit from XRF spectroscopy.

Metals and Alloys

When using metals and their alloys, their chemical composition must be known to ensure they will have the properties required for the application. XRF spectroscopy is used within the metal industry to provide a high level of quality control and consistency between batches. The sample preparation techniques that are used for XRF are also beneficial for metals and alloys as they require a high level of accuracy....
