Optical Emission Spectroscopy (OES) Analysis

Optical Emission Spectroscopy, 或OES分析, is a rapid method for determining the elemental composition of a variety of metals and alloys. im体育APP’s chemical analysis labs are equipped and ready to 评估 the properties of your material, as well as support OES on your site. 

OES analysis uses a sparking process, which involves applying an electrical charge to the sample, vaporizing a small amount of material. Once this spark occurs, a discharge plasma with a distinct chemical signature is created, allowing our experts to determine the elemental breakdown of the sample. The results of the analysis are given as a percentage breakdown of the constituent elements.

What is optical spectroscopy used for?  

Optical emission spectroscopy is an ideal choice for applications where knowing the exact, quantitative breakdown of solid material is required. The best material types f或OES分析 are metals that are soft enough to respond to the sparking process. Harder metals, which may be resistant to sparking, are better suited to other chemical analysis methods. The inherent accuracy and rapid delivery of results make OES analysis the ideal choice for lot verification testing of a wide range of alloys.

Arc Spark OES analysis 

Spark optical emission spectrometers (S-OES) are the ideal instruments for metal analysis. Optical emission spectrometry using Arc/Spark excitation is the reference technique for rapid,elemental analysis of solid metallic samples.

Our 从事专家 use the Arc Spark (point-to-plane) method to create an electrical spark that melts and evaporates the metal’s surface causing optical radiation with very specific frequencies (lines of emission). We provide metal composition analysis for the following application:

• 铁 & 钢及其合金
• Aluminum and its alloys
• 铜及其合金

现场OES分析 

作为我们 on-site Metallographic Analysis, im体育APP offers on-site Optical Emission Spectroscopy services for full chemical analyses of all metal alloys. We can measure the intensity of the frequencies through an optical system and determine the chemical composition of the metal at the surface. 我们的能力 also include more challenging on-site analysis, covering the UV light elements, 如:C, P, S, 和Sn, where the test room is purged with 99.998%纯氩. 

For materials that cannot be transported or parts that cannot be removed, our on-site OES analysis offers cost-effective solutions while delivering fast and accurate results.
