What is optical emission spectroscopy (OES)? | OES explained

Optical emission spectroscopy, or OES, is a well trusted and widely used analytical technique used to determine the elemental composition of a broad range of metals.

OES can analyze a wide range of elements from hydrogen to uranium in solid metal examples covering a wide concentration range, giving very high accuracy, high precision and low detection limits. The elements and concentrations that OES analyzers can determine depend on the material being tested and the type of analyzer used.

Compared to other analytical techniques, OES has many advantages: it’s fast and relatively easy to use, it measures a wide range of elements and concentrations in many different types of materials, including important elements such as carbon, sulfur, phosphorous, boron and nitrogen. It’s extremely accurate when measuring low levels of trace and tramp elements, and it’s low-cost.

I have done the chemical analysis of the sample by OES but did not understand how the composition came in 5min. But in the next 5 min understand the concept very clearly after watching this video. Thank you for this.

Nice explication, I'm French and I understand all. Thanks you. Have a nice day

Thank you for the explanation sir, so informative

Ah, wow, THAT'S the thing I've been looking for in all these exolanation videos at 4:30....the actual spectrum!! wow it's so complex.

Sir how the spectrometer defined by 8/16/24/32/40 elements ?

[brucewinningham]

Are these ICP-OES machines used widely in GeoChemistry please?

[footballCartoon]

I am still baffled..
Is this method uses Fourier transform method to capture/split (using monochromator) the light emitted from the arc lightning or spark to the sample?
If it is, would the monochromator move back and forth towards the light source from the sample?

What is the minimum concentration than can be measured by an OES

[dineshm]

Nitrogen is a gas, how can it be detected when this is a solid analysis method
