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.
Claims6
A method for preparing a sample of organic material for laser induced breakdown spectroscopy (LIBS), the method comprising:
- obtaining granular organic material, the granular organic material including an organic matrix;
- loading the granular organic material into an open ended cylindrical die, and applying pressure to the granular organic material that is loaded in the open ended cylindrical die to form the granular organic material into a consolidated mass that is a sample pellet, wherein the sample pellet is retained in the open ended cylindrical die such that the sample pellet presents an exposed end surface that is exposed in the open ended cylindrical die;
- applying heat to the exposed end surface of the sample pellet while the sample pellet is retained in the open ended cylindrical die to sear at least the exposed end surface of the sample pellet that is exposed through the open ended cylindrical die to induce a thermochemical decomposition of at least a portion of the organic matrix that is included in the sample pellet, to establish a seared surface of the sample of organic material.
