Plasma spectroscopy ICP-OES
ICP-OES plasma spectroscopy is an essential technique for elemental analysis in various industries. Using an inductively coupled plasma and an optical emission spectrophotometer, it allows detecting and quantifying multiple elements with high precision and speed. Álava Ingenieros offers advanced equipment such as Horiba Scientific’s Ultima Expert and Ultima Expert LT, ideal for applications in the pharmaceutical, food, metallurgy and environmental (rare earth analysis) industries. With the ability to simultaneously analyze multiple elements and provide accurate results, ICP-OES is essential to ensure quality and efficiency in industrial and research processes.
Description
ICP-OES is a technique that uses an inductively coupled plasma to ionize a liquid sample and a spectrophotometer to analyze the light emitted by the ionized elements. In this process, the sample is continuously introduced and converted into an aerosol by a nebulization system. This aerosol is transported by argon to the plasma torch, where it is subjected to high temperatures that raise the elements in the sample to higher energy states. When these elements return to their fundamental state, they emit electromagnetic radiation at specific wavelengths, generating atomic emission spectra that are measured to determine the concentration of each element present.
Basic principles of ICP-OES
- Nebulization and transport: the liquid sample is converted into an aerosol and transported to the plasma by a flow of argon.
- Ionization in plasma: in plasma, the sample is ionized due to high temperatures, reaching higher energy states.
- Radiation emission: ionized elements emit radiation at characteristic wavelengths when returning to their fundamental state.
- Detection and analysis: emission spectra are scattered by a diffraction grating and a detector measures the line intensities to quantify the elements present.
Advantages of ICP-OES spectroscopy
- High sensitivity and precision: allows the accurate detection and quantification of elements at very low concentrations.
- Wide dynamic range: can analyze a wide range of elemental concentrations.
- Speed and efficiency: it delivers fast results, which is crucial for industrial and research applications.
- Multielemental capability: allows simultaneous analysis of multiple elements in a single measurement.
ICP-OES applications
The ICP-OES technique is used in a variety of industries due to its ability to provide detailed and accurate elemental composition analysis. Some of the most common applications include:
Pharmaceutical industry: analysis of raw materials and final products to ensure purity and quality.
