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.

Abstract: A device comprises: a receptacle having a bottom wall portion closing a first end of the receptacle to delimit an inner space and having a receptacle opening at an opposite second end; a compartment for holding a lateral flow assay test strip, the compartment having a lower portion located closer to the first end than to the second end; a passageway in fluid communication with the lower portion of the compartment; and a lid configured to overlay the receptacle opening and comprising a body portion. A sample receiving portion is located in said body portion and is arranged in fluid communication with the inner space. The passageway is delimited by a first opening into the lower portion of the compartment and a second opening in the lid.

Abstract: A sampling device comprises a receptacle having an inner material receiving space defined by a side wall portion and a bottom wall portion and having a receptacle opening; and a sample container being adapted to close the receptacle opening when collocated with the receptacle. The sample container includes: a sample receiving portion which, when collocated with the receptacle is located in liquid communication with the inner material receiving space; a sample well positioned radially outside of the sample receiving portion in a direction perpendicular to a longitudinal axis, the sample well having a well opening; a liquid passageway for directing liquid from the sample receiving portion towards the well opening; a container having a container opening; and a liquid impermeable barrier for preventing liquid entering the container opening from the sample receiving portion.

Abstract: A Laser Induced Breakdown Spectrocopy (LIBS) system for the analysis of a sample pellet of a consolidated granular material retained in a tubular container may include a laser source configured to emit a pulsed laser beam towards an exposed surface of the sample pellet; and a sample station configured to hold the cylindrical tubular container in one or more orientations to present an exposed surface of the sample pellet towards the pulsed laser beam. The sample station may induce linear movement of the sample pellet along an axis and to expose a portion of the outer side surface of the sample pellet previously constrained through contact with an inner surface of the cylindrical tubular container. The sample station may induce rotational motion of the outer side surface of the sample pellet around the movement axis to present the portion of the outer side surface as the exposed surface.

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 system for accepting or rejecting a container containing a meat batch comprises a reader and a controller cooperating to effect the acceptance or the rejection of the meat batch. The reader is configured to interrogate a machine readable tag attached to the container to retrieve information stored thereon into the controller which is configured to respond to the information retrieved by the reader to access batch information comprising at least information indicative of a fat content of the meat batch, to compare the batch information with a criterion of a recipe related to a target fat content to determine a suitability of the meat batch for inclusion in a mix meeting the recipe, and to generate a control signal dependent the determination usable to effect acceptance or rejection of the meat batch as appropriate to the determination.
