What is the role of an ICP-OES analysis instrument? It is to examine the composition of substances. For this purpose, the device fundamentally converts liquid into light, and light into an answer. In order to accurately determine which chemical elements are present in a liquid sample, the device introduces the sample into a very high-temperature plasma. When the heat excites the atoms and ions of the sample elements, they emit light, which is captured by the spectrometer of the analysis instrument and separated into spectral lines. Typically, the intensity of this light is related to the concentration of elements present in the sample. This is crucial. By accurately measuring the light intensity, you can determine which elements are present in the sample and in what proportions. Now, let's take a look at the state-of-the-art SPECTRO ARCOS ICP-OES analysis instrument. Let's explain the mechanism step by step. The liquid sample is drawn into the peristaltic pump and is transformed into a spray of fine particle aerosols by the nebulizer. In the spray chamber, large liquid droplets are expelled, while fine droplets head towards the high-temperature plasma.

In plasma, aerosols of the sample vaporize, and the atoms and ions are excited, emitting characteristic wavelengths. The light is transferred to a sealed spectrometer without purge with high resolution and separated into specific wavelengths for each element to be measured. When the wavelengths hit the detector array, the light intensity is quantified for each different wavelength and converted into concentration units by high-performance software. This reveals the secrets of the sample, such as the elements included and their precise amounts. The process is complex, but the results are accurate. The next-generation ICP-OES analysis equipment, SPECTRO ARCOS, which produces reliable results, is an essential tool for your highly productive lab.
