We found a Raman peak in the silver powder around 1000 cm-1. What could be the origin of this peak?

As we know, for Raman spectroscopy, a change in dielectric constant is required w.r.t. phonons, which does not apply to metals. Therefore, pure metals are Raman inactive. Also, this 1000 cm-1 peak...

liquid Argon is recommended for ICP-OES because it's high purity and provide a continuous argon feed

Also you can use high purity gaseous Argon ( 99.999 %) but you need a sires of argon cylinders

Edward Russak

I use high purity Argon from cylinders.

Abdulgader Mohamed

economically high purity liquid argon is preferred
