Which wavelength to select in case of multiple peaks UV-Vis spectroscopy analysis of standard solution (e.g. Polyethylene)?
The one which has the best signal/noise ratio ?
The one which gives you the best LOD/LOQ ?
I think you will find that polyethylene is transparent (certainly looks that way to me). So visible will not work, but it may well absorb in the short wavelength UV (which cause degradation).
