ICP-OES vs ICP-AES –Is there a line that needs to be drawn here

  The terms "inductively coupled plasma optical emission spectroscopy" (also written as "ICP-OES") and "inductively coupled plasma atomic emission spectroscopy" (also written as "ICP-AES") are used interchangeably in a number of scientific publications (26, 27, 28). This is due to the fact that both of these phenomena represent the emission of photons from an ionized sample, which can be deconvoluted into signals from each of the component elements.
  
  How exactly does one go about analyzing the data obtained from an ICP-OES experiment, and what kinds of things can one glean from doing so?
  
  You should look at the intensity of the light emitted at particular wavelengths and then compare that to the calibration data in order to determine the concentration of atoms that are emitted at that particular wavelength, as stated in the general guidelines for the analysis of icp emission spectrometer data. These guidelines state that you should look at the intensity of the light emitted at particular wavelengths. The user is given the option to select multiple wavelengths on the vast majority of the instruments that are currently in use today. In order to accomplish this, the user should select wavelengths that are compatible with the emission signals emanating from the atoms that are of particular interest.29The process of identifying the components contained within the sample is typically an automated one, and it begins after the selection of the appropriate wavelength for the analysis being performed. This procedure has become significantly more complex over the course of the past few years in order to facilitate multivariate analysis and highly sensitive identification.30
  
  When analyzing ICP-OES data, there are a few other considerations that need to be addressed. One of these is the possibility of interferents, and the other is the ability of interferents to hinder the performance of the system. It is recommended that users utilize an internal standard in order to correct for variability from sample to sample as well as differences in the conditions under which samples are processed in order to get rid of unwanted interferences prior to analysis. This is done in order to ensure accurate results from the analysis.31Scandium and yttrium are two different elements that are frequently utilized in the process of establishing internal standards. These components were chosen because, in general, the wavelengths they emit do not overlap with those emitted by any of the other atoms that are present in the sample. After the internal standards have been successfully implemented, using the calibration data to compare the light intensity obtained from the sample to the light intensities of known sample compositions is something that can be done directly thanks to the information provided. The primary readout data from the ICP-OES are provided by this comparison. This data includes the different types of elements that were discovered in the sample as well as their relative ratios within that sample.
  
  On the left, you can see examples of typical line spectra that are produced by an ICP-AES instrument. The same spectra with an increase in magnification along the y-axis demonstrates that, despite being lines in the spectrum, they are still peaks and, as a result, can be affected by spectral interferences (right). This is demonstrated by the fact that when the magnification along the y-axis is increased, the same lines in the spectrum appear as peaks.
  
  Figure 2 shows, on the left side of the page, line spectra that are representative of ICP-OES. The same spectra with an increase in magnification along the y-axis demonstrates that, despite being lines in the spectrum, they are still peaks and, as a result, can be affected by spectral interferences (right). This is demonstrated by the fact that when the magnification along the y-axis is increased, the same lines in the spectrum appear as peaks. One possible solution to this problem is to make use of software that enables the selection of peaks that are unaffected by interference. This is one way to get around the problem.
  
  The advantages and disadvantages of utilizing the icp emission spectrometer method
  
  One of the most important advantages of the ICP-AES is that it can determine not only the different kinds of elements present in complex samples but also the proportions of those elements. ICP-OES, for example, has been used successfully to analyze the composition of crude oil, contaminated soil, and heavy metal mixtures, all of which would have been difficult to analyze using other methods. Other methods include:ICP-OES is a multi-step process, which explains why this is the case. ICP-OES also has the capability of detecting multiple elements simultaneously, which is another significant advantage of the method.37, 38; researchers have reported instances in which ICP-OES detected as many as 19 different elements during a single process of analysis.39ICP-OES has seen improvements in its general applicability as a result of developments in spectral deconvolution41 and calibration procedures17, as well as enhancements in its capacity to aerosolize a greater variety of sample types. These developments were made to improve the efficiency of detection efforts. Even if the sample being analyzed is radioactive, the icp optical emission spectrometer can be used to determine the elemental composition of the sample; however, additional measurements are required in order to determine the level of radioactivity that is present in the sample.
  
  42, 43As a conclusion, the simplicity of the ICP-OES has made it possible for it to be utilized in chemistry education settings,44 with solvents of both analytical reagent grade and spectral pure grade,45 and with relatively high throughput for sample preparation46 and analysis47, highlighting the ease with which the system can be used. In other words, the simplicity of the icp emission spectrometer has made it possible for it to be utilized in chemistry education settings.
  
  One of the most obvious disadvantages of the ICP-OES is that it requires the samples to be aerosolized before analysis can take place. This means that solid and liquid samples cannot be analyzed while they are still in their respective solid and liquid forms, despite the fact that the procedures for aerosolization have undergone significant advancements (refer to the section above for more information on this topic). In addition, ICP-OES is a destructive analytical method, which means that once the sample has been analyzed, it cannot be recovered in any way. This is a significant limitation of the method. Because of this, extremely rare or priceless samples cannot be analyzed using this method because there are not enough of them to go around. In addition, the development of a method making use of ICP-OES can be a process that takes a lot of time because it requires the completion of multiple steps, including the following:28(a) performing a rough analysis to obtain a general idea of the elements that are present in the sample; (b) selecting a wavelength based on that initial knowledge; (c) optimizing separation in such a way that signals from the various wavelengths have limited overlap; (d) comparing the method and system performance with an internal standard to validate them; and (e) conducting an analysis for spectral interferences and finding ways to eliminate those from the read-out wi; a rough analysis is performed to obtain ICP-AES requires expensive instrumentation for plasma generation, sample aerosolizing, and signal analysis, albeit at a relatively lower cost than other comparable methods such as ICP-MS,48 which means that access to this technique is necessarily limited.
  
  Despite the fact that the cost of this technique is relatively lower than the cost of other comparable methods such as ICP-MS,48 access to this technique is necessarily limited. Access to this technique is necessarily restricted due to the fact that despite the fact that it has a relatively lower cost than other comparable methods such as ICP-MS,48 this technique cannot be used by everyone.
