- the device comprises a measuring instrument chosen from the list defined by infrared ray spectrometers, laser ablation spectroscopes, fluorescence spectrometers at X-rays, RAMAN spectrometers.
- Infrared spectroscopy is a class of spectroscopy that deals with the infrared region of the electromagnetic spectrum. It covers a wide range of techniques, the most common being a type of absorption spectroscopy. As with all spectroscopy techniques, it can be used for the identification of compounds or to determine the composition of a sample. Since the acquisition instruments are miniaturized, they are transportable, even for outdoor use. With the increase in computer filtering and result processing technologies, samples in solution can now be measured precisely (water has a broad absorbance at the wavelengths of interest, which renders an unprocessed spectrum uninterpretable). Some instruments have their own databases, so identification can also be automated.
- FIG. 5 shows in detail the assembly of an IR spectrometer. 4 on the device according to the invention. More particularly, the IR spectrometer 4 is fixed on a support 220 and held by means of a tab 221, thus constituting the fixing 22.
- the support 220 is itself mounted on the mobile part 240 of the actuator 24, itself -even mounted on the plate 21.
- a connection box 241 makes it possible to electrically connect the various instruments to the control PC. This box has a USB socket and three specific sockets adapted to the various instruments. Actuator 24 is controlled by the ECU.
- Laser-induced plasma spectrometry is a very weakly destructive analytical technique (micron surface ablation) whose principle is based on the use of non-ionizing monochromatic radiation.
- 1-A high energy pulsed laser is focused on the sample.
- the high temperature of the laser on the sample results in the ablation of a small volume of material in a plasma.
- the plasma contains excited atoms and ions from the sample.
- the environment is controlled: air, argon, helium.
- the spectrometer separates all the wavelengths using high-resolution dispersive optics then detects them with a charge-coupled sensor (CCD) containing a very large number of pixels aligned in arrays of photodiodes.
- CCD charge-coupled sensor
- Each pixel corresponds to a precise and known wavelength.
- the intensity collected by each pixel is proportional to the quantity of photons collected.
- the wavelength (X axis) and the intensity (Y axis) make it possible to display a histogram (spectrum) characteristic of an ablated point (therefore of the sample if it is homogeneous).
- 5-Thus if the pixel considered corresponds to the wavelength of a de-excitation characteristic of an electronic transition of an element, an appropriate calibration can calculate the mass concentration of this element in the matrix. By processing the entire spectrum, it is possible to deduce the concentration of all the elements present from hydrogen to uranium (if they have been calibrated).
- X-ray fluorescence spectrometry is a chemical analysis technique using a physical property of matter, X-ray fluorescence.
- the matter When we bombard matter with X-rays, the matter re-emits energy in the form, among other things, of X-rays, this is X-ray fluorescence, or secondary emission of X-rays.
- the spectrum of X-rays emitted by the material is characteristic of the composition of the sample, by analyzing this spectrum, one can deduce the elemental composition, that is to say the mass concentrations of elements.
- WD-XRF wavelength dispersive X-ray fluorescence spectrometry
- ED-XRF energy dispersive X-ray fluorescence spectrometry
- FIG. 6 illustrates an attachment 22 of an X-ray fluorescence spectrometer to a device according to the invention.
- the head of the X-ray fluorescence spectrometer is fixed on a support 222' itself mounted on a plate 221'.
- Four threaded rods 223' are screwed onto this plate.
- the rods pass through two horizontal bars 220' which are integral with the mobile part 240 of the jack Z.
- Springs inserted between the support plate and the horizontal bars make it possible to dampen the contact between the head of the spectrometer and the part to be analyzed. This contact must be flexible (so as not to induce mechanical stresses on the instrument and the sample) and firm (to be able to actuate the contact which allows the instrument to send its X-ray flux).
- Raman spectroscopy or Raman spectrometry
- Raman microspectroscopy are non-destructive methods for observing and characterizing the molecular composition and external structure of a material, which exploits the physical phenomenon that a medium slightly changes the frequency light flowing through it. This frequency shift, known as the Raman effect, corresponds to an exchange of energy between the light ray and the medium, and provides information on the substrate itself.
- Raman spectroscopy involves shining monochromatic light onto the sample and analyzing the scattered light. The information obtained by the measurement and analysis of this shift makes it possible to trace certain properties of the medium, by spectroscopy.
- Coherent Raman scattering does not use an observation of spontaneously scattered light during molecular collisions, but the coherent amplification of a second ray of different frequency and temporally incoherent from the excitatory ray.
- This technique is complementary to infrared spectroscopy. Both allow to study the vibrational modes of a molecule, but the selection rules for the two spectroscopies can be different depending on the molecular symmetry. At molecules with a center of symmetry, no vibrational mode is observable at the same time at both spectroscopies. Some modes are active in Raman only and others in infrared only.
- FIG. 7 illustrates an assembly of a RAMAN spectrometer on a device according to the invention.
- the round head of the spectrometer is blocked in the cylindrical hole of a plate which is fixed to the base of the movable part 240 of the actuator Z.
- the spectrometer is held in balance by two nylon screws which tighten its head on the plate .
- the spectrometer is connected to the USB socket of the 241 box. Its power supply is fixed on the "instrument power supply support"
- Such a device makes it possible to carry out the analysis directly in a mine, on an archaeological site or even a geological site without the need to carry out the drilling of the support to extract a core.
- Such a device allows horizontal analysis but also inclined analysis up to the vertical and allows analysis both on floors and on walls.
- control unit controls, according to a program executed by the computer, the movement of the measuring instrument, in at least one of the three directions (X), (Y), (Z), so as to successively analyze all the samples or all the cores.
- the analysis instrument can be variable depending on the mapping to be carried out: infrared, LIBS, Raman, X-ray fluorescence, high resolution photography. It is also possible to combine several analysis instruments so as to specify the chemical composition of the analyzed zones.
- the device according to the invention makes it possible to produce maps of minerals with chemical and optical characterization instruments (Infrared, Laser ablation spectroscopy (LIBS), Raman, X-ray fluorescence, high resolution photography).
- chemical and optical characterization instruments Infrared, Laser ablation spectroscopy (LIBS), Raman, X-ray fluorescence, high resolution photography.
- the nature of the mineral elements can be of all types: geological samples, archaeological samples (mosaics, paintings for example).
- the device according to the invention makes it possible to work on plane or quasi-plane samples, of centimeter to metric size, of geological cores.
- the positioning of the device can be horizontal or inclined to the vertical. It enables analyzes to be carried out both on the ground and on the walls (mine working faces, for example).
- the device according to the invention makes it possible to eliminate the tedious and repetitive nature of manual analyses. For example, for X-ray fluorescence analyses, the analysis times can reach several minutes for the same point without moving.
- the system can be transported by a van or any other vehicle under 3.5 T.
