Comparison of Preparation Methods for Determination of Powder Samples by X-ray Photoelectron Spectroscopy

The effects of different sample preparation methods on the test results of conductive samples of lithium and non-conductive samples of milk powder were discussed. The experimental results showed that conductive copper film is better for the conductive sample lithium electrical material, and conductive or non-conductive film for non-conductive sample milk powder is better for the conductive or 3M film.
