The different types of spectrometry

swe spectrometrie icp laboratoire

Inductively coupled plasma (ICP)

Inductively Coupled Plasma (ICP), also known as ICP-AES (Atomic Emission Spectrometry) or ICP-OES (Optical Emission Spectrometry), is used to analyse many elements simultaneously, with extremely low detection levels, in a wide variety of markets, including food and beverage, metals, pharmaceuticals, geology, water and cement. ICP works using an Argon plasma, into which the atomized liquid sample is injected.

Atomic absorption spectroscopy (AAS)

Atomic absorption spectroscopy (AAS) uses the absorption of light to measure the concentration of atoms in the gas phase, which absorb light and make transitions to higher energy levels. The amount of absorption determines the concentration of a particular component. The gases used in AAS are Nitrogen and Argon.


Nuclear magnetic resonance spectroscopy (NMR)

Nuclear magnetic resonance (NMR) spectroscopy is a research technology in analytical chemistry, used to analyse the physical and chemical composition of materials. Air Liquide is the only gas supplier with a special helium reserve in Europe to guarantee a continuous supply without interruption.


Infrared spectroscopy (IR)

Infrared spectroscopy is the measurement of the interaction of infrared radiation with matter by absorption, emission or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid or gaseous form. Air Liquide offers Nitrogen and Air of different qualities for the operation of IR equipment.
