tin filters quality

On average seawater contains 1-10 ppt of tin, and river water contains 6-40 ppt.The Lacuta seaweed generally contains 12 ppb of tin, and mussles contain up to 160 ppb (dry mass). Dissolved in water tin generally occurs as SnO(OH) 3-, and in both seawater and freshwater mono-, di- and trimethyltin compounds can be found.This are partially decomposed to volatile compounds.

Or if scattered then degrade the image …

To absorb preferentially the energy fluence below the K edge of tin, including the characteristic x-rays of tin, a copper filter is quite efficient. The K edge of copper is at 9 keV, and therefore, the photons below 29 keV are strongly absorbed by the copper filter as seen in curve C of Figure 7.1. The very-low-energy characteristic x-rays ...
