LABORATORY  INSTRUMENTS GALLERY

Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), is an analytical technique used for the detection of chemical elements. It is a type of emission spectroscopy that uses the inductively coupled plasma to produce excited atoms and ions that emit electromagnetic radiation at wavelengths characteristic of a particular element. It is a flame technique with a flame temperature in a range from 6000 to 10000 K. The intensity of this emission is indicative of the concentration of the element within the sample.

​

Atomic Absorption Spectroscopy (AAS) is a spectral analytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state. AAS can be used to determine over 70 different elements in solution.

​

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is a type of spectroscopy that uses the inductively coupled plasma to produce ions that travel though an electrostatic focuser to a mass analyzer and counted. As the charge of the focuser changes, different elements are allowed to reach the detector. The plasma operates at a temperature of nearly 10,000 C or 18,000 F.
