Abstract: A LIBS analyzer (2) comprises a focusing lens arrangement (6); a laser (8) for propagating a laser beam (L) through the focusing lens arrangement (6) to be focused at its focal plane (F); a detector (10) for generating optical intensity data; a translation mechanism (22) for varying a location of the focal plane (F); and a controller (14) for automatically controlling the translation mechanism (22) to achieve an optimum position where the focal plane (F) and an upper surface (18) of a sample (20) are coincident, as calculated by the controller (14) from an application of a mathematical transform, correlating optical intensity with optimum position, to optical intensity data from plasma created by the laser beam (L).

Abstract: A press (2) for preparing a pellet of granulated material for laser induced breakdown spectroscopy comprises a tubular die (8) and a piston (4) arrangement, the tubular die (8) being formed with an inner surface (14) along which the piston (4) can slidably move and which is delimited by an open first end (10) of the tubular die (8;30;48a-d) and an opposing open second end (12) of the tubular die (8). The press (2) further comprises a removable end cap (18) having at least one flat face (24) for sealing the second end (12) of the tubular die (8).

Abstract: A Method of Preparing an Organic Material Sample for LIBS Analysis and a Searing Device for Use in the Same An organic material sample is prepared for LIBS analysis by loading a sample pellet (508) comprising a compressed granular organic matrix into a holder (506) of a searing device (500) with an exposed surface (510) of the sample pellet (508) accessible to optical and to thermal radiation; searing the sample pellet (508) by directing thermal radiation from a heating unit (504) to the exposed surface (510); directing optical radiation from a reflectance unit (514) to the exposed surface (510) and measuring searing induced changes in the reflectance of the exposed surface (510); and controlling the heating unit (504) to direct thermal radiation to the exposed surface (510) for a time calculated by a data processor (516) in dependence of the measured searing induced changes in the reflectance.
