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.
