Abstract
A method for preparing a sample of organic material for laser induced breakdown spectroscopy (LIBS) may include obtaining granular organic material, forming a portion of the granular organic material into a sample pellet, and searing the organic material. The searing may include searing only an exposed end surface of the sample pellet on which LIBS analysis is to be performed. The method may include pressing the seared sample pellet to consolidate the material comprising the seared end surface.
Claims5
A method for preparing a sample of an organic material for laser induced breakdown spectroscopy (LIBS), the method comprising:
- receiving a sample pellet of the organic material, the organic material including an organic matrix, the sample pellet including an end surface;
- and
- applying heat to the end surface of the sample pellet to sear at least the end surface of the sample pellet to induce a thermochemical decomposition of at least a portion of the organic matrix that is included in the sample pellet, to establish at least a seared end surface of the sample pellet,
- wherein the receiving the sample pellet includes receiving the sample pellet in an open ended cylindrical die such that the end surface of the sample pellet is exposed in the open ended cylindrical die as an exposed end surface, and
- wherein the applying heat to the exposed end surface of the sample pellet sears at least the exposed end surface of the sample pellet that is exposed through the open ended cylindrical die to establish at least the seared end surface of the sample pellet.
