[Analysis Case] Component Analysis of Aluminum Foil Surface

Evaluate the difference between glossy surfaces and matte surfaces.

Aluminum foil is produced by rolling two sheets together, where the outer side in contact with the rollers has a glossy surface, while the inner side, where the aluminum sheets touch each other, has a matte surface. We compared the components present on the extreme surfaces of each side. Common organic secondary pollutants such as PDMS (polydimethylsiloxane), BHT (antioxidant), DOP (plasticizer), amines (m/z 182, 242), amides (m/z 256, 284), and carboxylic acids (m/z 255, 283) were not observed. There was a slight tendency for Fe and organic materials (such as hydrocarbons) to be stronger on the glossy side, while substances like SO4 showed a slightly stronger tendency on the matte side.
