Dear Judith,

Your answer describe the property of ToF-SIMS. But my question remains steady  condition. Will you provide the some link or research paper which satisfy my question.

Hi, 

First of all, what MW are you expecting to see?

You have polymer like signal in most of the spectra you attached.

You have a polymer type of signal in the bottom right spectrum (all signal are separated by 28 Da).

In the bottom left you have another serie, separated by 2 Da, which may represent the same type of molecule with different insaturations.

You wrote: "In mass spectrum analysis (ToF-SIMS) several count peaks are obtained therefore difficult to analyze"

Maybe we should clarify this: Mass Spectrometer will give you a lot of peaks. Always.

And polymers will give you ion series. Always.

To answer your question: yes, you can use SIMS to analyse polymers. But you need to understand first what exactly you are doing with the technique you are using.

Here a good starting point

Thank you Dr. Fabrizio. Your significance signature provides valuable knowledge to me. I expecting another answer from your side as well as related to ToF-SIMS. Your kind consideration also required for the same. My question is " Will oxygen sputtering in depth analysis certainly modify the chemistry of conducting polymer composites. The same question also attached with RG site.

With great regards. 

Thank you Dr. Judith. I am trying to search or download SDBS system from the net.

With great regards. 

Well, I cannot answer your question because I don;t have a sample to evaluate.

If you sputter oxygen on a polymer, you should see somewhat of an oxidation process. Therefore, I would guess that you original polymeric serie will have a shift (positive).

Do you have a control and a treated sample to compare? 

Dr. Donnarumma,

Poly(diaminonaphthalene) doped poly(vinyl alcohol) sample I used to measure for the multi-layer structure as well chemistry (structure) inside the film. 

With regards.
