ICP-AES: Part C: What is Inductively Coupled Plasma (ICP)?

[@jacksmith3095]

Excellent video, very helpful... My Masters thesis is in ICP electrothermal thrusters for satellite applications; rare to find such a concise video explanation. 👏

ICP plasma is quite pretty, but its also pretty high in UV and just plain bright. Make sure you got your shades on

Hi Dr, I have a question, what's the difference using CCD detector and using a PMT detector?

[@mirkoleone94]

I have a question: - in emission spectroscopy normally the atoms must be excited (with the electrons being promoted to the excited state) but not ionized, since the emission spectra are different from atoms to ions. In fact in the ICP-OES the plasma, containing free electrons, hinders through electrostatic repulsion the loss of electrons from our analyte, hence, the ionization. - In ICP-MS however with must have the ionization of our sample for the separation and determination of the charged fragment according to their m/z ratio. First of all, is this right? Then, how can I correctly explain this? Maybe in different point of the plasma, at different temperature, I have different excited atoms / ions ratio? Thanks to anyone willing to answer my question.

Thanks this helped alot

Hi @Oussama Oussama, thanks for watching. Glad that the video helped.

One question about the droplets separation Wouldn't that separation affect the integrity of our sample ?

[@FrancisChongYY]

That's a good question. Typically it won't be affected as the samples prepared should be quite homogeneous.

What is the use of aerosol?

[@wardsmith2542]

Carries the total dissolved solids, ie the "sample" material. Also helps cool the inner channel of the plasma zone
