    Abstract: A LIBS analysis system comprises a focusing lens arrangement having a focal plane; a laser for propagating a laser beam through the focusing lens arrangement to be focused at the focal plane; a detector for generating an output that is proportional to an intensity of incident electromagnetic radiation that is incident on the detector; a translation mechanism configured to cause a relative movement of the sample holder and the focusing lens arrangement to vary a position of the focal plane along the optical path with respect to the sample holder; and a controller configured to automatically control the translation mechanism to cause the relative movement of the sample holder and the focusing lens arrangement to achieve an optimum position at which the focal plane and an analysis region of the upper surface intersecting the optical path are at or are close to coincidence.

    Abstract: A method of analysing a foodstuff sample using laser-induced breakdown spectroscopy, comprises: ashing the foodstuff sample to generate an ash residue; and forming the ash residue into a layered pellet based on: loading at least the portion of the ash residue into a die, loading a support material into the die as a layer covering a second surface of the portion of the ash residue subsequently to loading at least the portion of the ash residue into the die, and compressing the portion of the ash residue and the support material in the die to form the layered pellet, such that a first surface of the portion of the ash residue at least partially defines the first surface of the layered pellet and the portion of the ash residue is undiluted by the support material at least at the first surface of the portion of the ash residue.

    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.
