Hi all,

I would ask about ICP-OES system, I am using it for metal detection in mineralized aliquots of soil and waste samples.

I am using an old method developed in my current lab, but I would like to improve it to obtain a better signal to noise ratio and lower LOD. So my question is:

Which are the variables to take into account for the method optimization?

I have considered yet:

- the wavelengths (I will perform proofs at different recommended WLs for every metal)

- the radial and axial mode (I will use axial because I saw that the LODs are lower in such a condition)

Is there any other parameter which I would consider? For example: is the time of acquisition important in the increase of the S/N ratio?

Thanks a lot to everyone who can give me some advice about that.

Matteo
