Scraped with Single Edged Razor Blade

Scraped with Single Edged Razor Blade

• A freshly sanded and solvent cleaned single edged razor blade is used to scrape away a few microns of a surface exposing clean fresh bulk for analysis. 
• This method can be applied to many materials, including metals.
• To be useful, the area of interest should be scribed with a 4-5 mm circle, and then the inside of the circle is scraped with the single edged razor.
• The scribed area must be uniformly scraped over an area that is at least 2 mm in diameter.
