    摘要: 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.

    摘要: A hydrodynamic focusing device comprises first and second flow channels; a wall at least partially defining an envelopment region connected in-line between the first and second flow channels which collectively define a flow direction extending therethrough; and a chimney comprising a body and a sample fluid inlet, extending from the wall and into the envelopment region. The sample fluid inlet faces at least partially perpendicular to the flow direction in the envelopment region, such that the sample fluid inlet is configured to supply a sample fluid into the envelopment region in a direction that is at least partially perpendicular to the flow direction. The body and the sample fluid inlet each have an elongate profile which has a rounded leading edge facing the first flow channel and opposing long edges connecting the leading and trailing edges and tapered towards the trailing edge.

    摘要: An analysis instrument comprises a sample receiving section for receiving samples provided by a plurality of users, an analysis section operable to receive an aliquot of each received sample, perform an analysis of each received aliquot, and generate an output based on the analysis, and a presentation section adapted to present the output in a human discernable format. The analysis instrument further includes an identification section adapted to autonomously generate an identifier unique to each user and each sample provided thereby and to supply each identifier for presentation by the presentation section in a human discernable format together with a portion of the output that corresponds with one or more samples provided by a user to which the identifier is unique. Each identifier consists of one or more graphic symbols, one or more colours, and/or one or more numbers.

    摘要: A method of standardizing an output of an electrical property sensor includes calculating a reference magnitude (Condr) of an electrical property of an electrically conductive liquid, based on obtaining, by a spectrometer, spectral data resulting from an interaction of light with the electrically conductive liquid, and applying, in a data processor, a mathematical model to the spectral data to calculate the reference magnitude (Condr) of the electrical property, wherein the mathematical model links the spectral data to magnitudes of the electrical property; comparing, in the data processor, a measured magnitude (Condm) of the electrical property of the electrically conductive liquid with a reference magnitude (Condr) of the electrical property, wherein the measured magnitude (Condm) of the electrical property is obtained with the electrical property sensor; determining, in the data processor, a standardization factor (F) dependent on a ratio of the reference magnitude (Condr) and the measured magnitude (Condm).

    摘要: 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.
