Electrothermal Vaporization ICP Optical Emission Spectroscopy (ETV-ICP-OES)

Electrothermal Vaporization ICP Optical Emission Spectroscopy (ETV-ICP-OES) uses high temperature plasma to liberate free atoms and ions from a vaporized sample in order to conduct elemental optical spectroscopic examination. When analyzing trace elements in a number of applications, including the examination of coal, metals and alloys, biomaterials, and the environment, the ETV-ICP-OES technique is highly helpful. Through its extensive network of laboratories, Infinita Lab, USA, provides this test to customers in the USA and all around the world.

Frequently Asked Questions

ETV-ICP-OES is an analytical technique that combines electrothermal vaporization (ETV) with inductively coupled plasma optical emission spectroscopy (ICP-OES) to detect and quantify trace elements in various sample types, including solids, liquids, and powders.

ETV-ICP-OES can analyze various sample types, including solid materials (metals and ceramics), liquid samples (biological fluids and environmental samples), and powders.

The process involves vaporizing the sample in an electrothermal device, transporting the vapor into a high-temperature plasma where atoms are excited, and then detecting the emitted light using a spectrometer to identify and quantify the elements present.

ETV-ICP-OES is widely used in industries such as environmental monitoring, materials science, metallurgy, and industrial quality control, where accurate trace element analysis is critical.

Detection limits can vary depending on the element and matrix. Still, ETV-ICP-OES can detect elements at parts-per-billion (ppb) or parts-per-trillion (ppt) levels.
