I. Introduction
A. Background
In analytical chemistry, Inductively Coupled Plasma Optical Emission Spectroscopy (ICP OES) is a powerful technique used to determine elements in a sample. It utilizes plasma to excite atoms and ions, which emit characteristic wavelengths of light that are then analyzed to identify and quantify elements present. One important aspect of ICP OES is the precise measurement of these wavelengths.
B. Purpose
The purpose of this article is to present a comprehensive ICP OES wavelength table that contains the most commonly used wavelengths for each element. This table serves as a reference for scientists and analytical chemists working in the field, aiding them in the accurate identification and measurement of elements in samples.
II. Methodology
A. Instrumentation
ICP OES instruments consist of several components, including a plasma torch, nebulizer, spectrometer, and detector. The spectrometer is calibrated to measure the intensity of emitted light at specific wavelengths. Typically, a polychromator is used, allowing for the simultaneous measurement of multiple wavelengths.
B. Sample Preparation
Prior to analysis, samples are first prepared by digestion, dilution, or other appropriate methods. The resulting solution is then introduced into the ICP OES instrument, where it is aerosolized and introduced into the plasma torch.
C. Data Collection
The emitted light from the plasma is focused onto the detector, which converts the light into electrical signals. These signals are then processed and analyzed to determine the intensity at each wavelength. Data collection is done for multiple wavelengths simultaneously to improve accuracy and efficiency.
III. Results and Analysis
A. Table of Wavelengths
