Abstract

A multi-technique and pluri-decimetric chemical mapping method and device for studying a set of specimens, core samples or indeed a surface. The device includes a control computer, a control unit, a measurement instrument, at least one longitudinal rail extending in a direction referred to as longitudinal direction, a support mounted for translational movement on the longitudinal rail in the longitudinal direction, a plate mounted for translational movement on the support in a transvers direction and perpendicular to the longitudinal direction, a fixing intended for fixing the measurement instrument and mounted for translational movement on the plate in a direction referred to as vertical direction, mechanisms for bringing about the translational movement of, respectively, the support, the plate and the fixing, these mechanisms being governed by the control unit.

First claim

1 - 12 . (canceled)

13 . A multi-technique and pluri-decimetric chemical mapping device for studying a set of samples, cores or a surface, wherein said device includes a PC drive computer, a control unit ECU, a measuring instrument, at least one longitudinal rail extending in a so-called longitudinal direction, a support translatably mounted to said longitudinal rail in said longitudinal direction, a plate translatably mounted to said support in a so-called transverse direction perpendicular to said longitudinal direction, a fastener provided for fastening the measuring instrument and translatably mounted to said plate in a so-called vertical direction, means for actuating translation of the support, the plate and the fastener respectively, said means for actuating translation being slaved to the control unit ECU.

14 . The multi-technique and pluri-decimetric chemical mapping device according to claim 13 , wherein the measuring instrument is selected from the list defined by infrared ray spectrometers, laser ablation spectroscopes, X-ray fluorescence spectrometers and RAMAN spectrometers.

15 . The multi-technique and pluri-decimetric chemical mapping device according to claim 13 , further comprising a bench extending along the longitudinal direction and to which the at least one longitudinal rail is fastened.

16 . The multi-technique and pluri-decimetric chemical mapping device according to claim 15 , wherein the bench includes a conveyor capable of moving the set of samples or cores in the so-called longitudinal direction.

17 . The multi-technique and pluri-decimetric chemical mapping device according to claim 16 , further comprising a compartmentalised tray provided for accommodating a set of samples, and/or a crate provided for accommodating cores.

18 . The multi-technique and pluri-decimetric chemical mapping device according to claim 17 , wherein the bench includes a set of stops and wedges for blocking and wedging said tray and/or said crate.

19 . The multi-technique and pluri-decimetric chemical mapping device according to claim 13 , wherein the support comprises at least one transverse rail to which the plate is translatably mounted in the so-called transverse direction.

20 . The multi-technique and pluri-decimetric chemical mapping device according to claim 13 , wherein the means for actuating translation of the fastener, the support and the plate respectively are electric motors.

21 . The multi-technique and pluri-decimetric chemical mapping device according to claim 13 , wherein the support is provided with means for fastening said support to a surface.

22 . The multi-technique and pluri-decimetric chemical mapping device according to claim 13 , further comprising a Point-Line-Plane system, including a fixed base, a movable base, three balls, two of which are housed respectively in a trihedron and a V-shaped groove, three screws passing through the movable base and dedicated respectively to securing one of the balls.

23 . A multi-technique and pluri-decimetric chemical mapping method for studying a tray of samples or cores, using a device in accordance with claim 18 , wherein the tray filled with a set of samples, or the crate filled with cores, is positioned manually on the bench, the tray or the crate is then blocked when the bench includes a set of blocking and clamping stops and wedges, then the control unit ECU drives the movement of the measuring instrument in at least one of the three directions, according to a programme run by the PC computer, so as to successively analyse the set of samples or the set of cores.

24 . A multi-technique and pluri-decimetric chemical mapping method for studying a surface, using a device in accordance with claim 21 , said device further including a measuring instrument selected from the list defined by infrared ray spectrometers, laser ablation spectroscopes, X-ray fluorescence spectrometers, RAMAN spectrometers, characterised in that the support is fastened to the surface by the fasteners, and then the control unit ECU drives the movement of the measuring instrument in at least one of the three directions, according to a programme run by the PC computer, so as to analyse a predefined zone of said surface.
