Optical emission spectroscopy (OES), Spark emission spectrometer ,also called atomic emission spectroscopy (AES) or arc spark emission spectroscopy, is an important tool for fast and accurate elemental analysis of metals and semiconductors. Optical emission spectrometry involves applying electrical energy to a metal sample to excite the evaporated and vaporized atoms. In this case, "applying electrical energy" means an electrical discharge between the sample and an opposing electrode.
Introduction
Optical emission spectroscopy (OES), Spark emission spectrometer ,also called atomic emission spectroscopy (AES) or arc spark emission spectroscopy, is an important tool for fast and accurate elemental analysis of metals and semiconductors.
Optical emission spectrometry involves applying electrical energy to a metal sample to excite the evaporated and vaporized atoms. In this case, "applying electrical energy" means an electrical discharge between the sample and an opposing electrode.
Spectral lines:
These excited atoms and ions in the discharge plasma create a unique emission spectrum for the element, as shown on the right. It can be seen that even a single element generates numerous emission spectral lines.
Therefore, the light generated by the discharge can be said to be a collection of the spectral lines generated by the elements in the sample. This light is split by a diffraction grating to extract the emission spectrum for the target elements. The intensity of each emission spectrum depends on the content of the element in the sample. The detectors (photomultiplier tubes) measure the absence or presence of the spectrum extracted for each element and the intensity of the spectrum to perform the qualitative and quantitative analysis of the elements.

In the broader sense, optical emission spectrometry includes ICP optical emission spectrometry that uses an inductively coupled plasma (ICP) as the excitation source. The terms "optical emission spectrometry" or "photoelectric optical emission spectrometry," however, generally refer to optical emission spectrometry using spark discharge, direct-current arc discharge, or glow discharge as excitation discharge.

JB-750 optical emission spectrometers feature Pulse Distribution Analysis (PDA) to enhance the measurement reproducibility (accuracy). This method involves statistically processing the emissions from the spark pulses obtained from spark discharges in an argon atmosphere. The optical emission spectrometer achieves rapid elemental analysis of solid metal samples, making it an indispensable instrument for the control of steel making and aluminum metallurgy processes.
