ICP analysis (ICP-MS and ICP-AES/ICP-OES) in a laboratory
What is ICP analysis?
ICP, short for "Inductively Coupled Plasma", is an inductively coupled plasma analytical technique used to measure the content of an inorganic element in a sample. This technique is applicable to all types of elemental chemical elements.
ICP sample analysis consists of several steps. Firstly, the solid sample must be dissolved using a strong acid, a mixture of strong acids or microwaves. This is known as mineralisation. The preparation is then vaporised in argon plasma and heated to very high temperatures. These thermal excitations lead to ionisation and separation of the elements, making it possible to characterise and detect each element, depending on the analysers used.
Some fifteen ICPs to serve your industries
ICPs coupled to Atomic Emission Spectrometers (ICP-AES or ICP-OES) measure the wavelengths emitted by ions.
Sensitivity: High for high and medium concentrations.
Applications: Quantitative analysis of elements and traces, and industrial quality control.
ICP coupled with Mass Spectrometers (ICP-MS or ICP-MS/MS) for the analysis of elements according to their charge and mass.
Sensitivity: Very high, suitable for traces and ultra-traces.
Applications: Trace and ultra-trace analysis, e.g. for the environment or pharmaceuticals.
Did you know?
ICP MS-MS is a technique identical to ICP-MS, which uses new intermediate gases to suppress powerful interferences, even in the most difficult matrices. This technique also has an even lower detection limit than conventional ICP. It can even be used to measure certain alkalis at very low quantification limits.
FILAB is the first independent, private laboratory in France to be equipped with an ICP-MS/MS.

Our FAQs
ICP coupled with atomic emission spectrometers (ICP-AES) is an analytical tool that can be used for the elemental analysis of samples. The combination of ICP and AES provides a highly sensitive and accurate method for analysing the concentrations of many different elements present in a sample. The technique is widely used in the metallurgy, pharmaceutical and food industries, etc. ICP-AES has been widely adopted by laboratories around the world because of its accuracy and cost-effectiveness.
This method involves introducing a sample into an ICP source that excites the atoms in the sample with an electric arc or laser beam to produce characteristic emission lines based on the atomic structure of each atom present. These emission lines are measured and analysed to determine the concentration of each element in the sample. The ICP-AES method is capable of detecting most elements at concentrations as low as parts per million.
In addition to its accuracy and cost-effectiveness, one of the advantages of the ICP-AES method is that it can be used on a variety of sample types - solid samples, liquid samples or even gases can be analysed. It also requires minimal sample preparation and very little instrument maintenance. For these reasons, ICP-AES has become one of the most popular techniques for elemental analysis in many industries.
Inductively Coupled Plasma (ICP) spectrometry is a technique used to measure the concentration of elements in samples. It involves introducing a sample into an ICP source, which excites the atoms in the sample with an electric arc or laser beam and produces characteristic emission lines based on the atomic structure of each element present. These emission lines can then be measured and analysed to determine the concentration of each element in the sample. ICP is an accurate and cost-effective method for elemental analysis and is widely used by laboratories around the world.
ICP spectroscopy has many applications in different sectors and fields. It can be used to analyse soil, wastewater, food and other environmental samples. It is widely used in the pharmaceutical industry to measure trace elements in drugs, as well as for quality assurance purposes. ICP spectroscopy can also be used in forensics and archaeology to analyse samples from crime scenes or ancient artefacts. It is also a valuable tool for the analysis of precious metals, helping companies to determine the exact composition of gold, silver and platinum alloys. In general, ICP spectroscopy can be used for many different analytical applications requiring elemental analysis.
The combination of ICP-AES and ICP-MS makes it possible to determine a wide range of inorganic elements and elemental impurities in a single run, with extreme reliability and accuracy (in the ppt to ppb range, depending on the matrix).
ICP-MS and ICP-MS/MS are two techniques for the accurate identification and quantification of chemical elements, even at very low concentrations.
While ICP-MS is widely adopted for its ability to detect trace elements in a multitude of materials, ICP-MS/MS stands out for its ability to eliminate interferences and provide more reliable results in complex matrices. This latter feature makes ICP-MS/MS particularly interesting when the purity and exact composition of materials are critical, as in the pharmaceutical industry for drug safety and contaminant control.
