SSIMS organic monolayer

Preparation of monolayers of organic materials on noble metal substrates leads to high secondary-ion yields and can even allow the detection of organic materials at levels that would otherwise remain below the detection limits. Three properties can be identified that make noble metals such exceptional SSIMS and SNMS substrates (I) enhanced desorption efficiency, (2) cation-ization and (3). stability and nonreactivity.
