In this paper the authors analyse powders using a variety of preparation methods - mixing with epoxy (glue), adhesion to double sided tape and pressing into soft metal (Copper) tape. As carbon was a key element for the analysis, double sided tape was chosen - large C signal in epoxy glue and damage to particles by pressing into tape. Results for W and C were compared to XRF analysis, showing LIBS had better accuracy
