“…In an effort to overcome the limitations of single-spectroscopy uses for mineral identification and to exploit the synergistic effect of complementary atomic and molecular information, several configurations of LIBS-Raman analytical techniques have been efficiently integrated into single instruments proposed for mineralogical and geochemical analyses already. ,,,,, Nevertheless, the format of the output data in the simultaneous acquisition of combined signals is a key factor for their further utilization. The simple use of a single detection system leads to the gathering of atomic emission and molecular scattering in a single spectrum.…”

“…Much has been said so far about the gains resulting from the combined use of atomic and molecular information from the point of view of overcoming the constraints of LIBS and Raman operating alone. Although several attempts have been made, − to date, there has not been any published research on the gathering of remote, instant, and simultaneous emission and scattering from single spots on the target as perfectly isolated signals to enhance the geochemical categorization scheme of rock constituents on the basis of cation–anion pairs in a hostile extraterrestrial environment. The effects of the critical parameters involved on the simultaneous spectral data acquisition, the possible conflicting issues affecting the performance of both measurement modes, as well as how such information can be associated and exploited to deal with the goal pursued will be detailed.…”

A single platform, integrated by a laser-induced breakdown spectroscopy detector and a Raman spectroscopy sensor, has been designed to remotely (5 m) and simultaneously register the elemental and molecular signatures of rocks under Martian surface conditions. From this information, new data fusion architecture at decisions level is proposed for the correct categorization of the rocks. The approach is based on a decision-making process from the sequential checking of the spectral features representing the cationic and anionic counterparts of the specimen. The scrutiny of the LIBS response by using a moving-window algorithm informs on the diversity of the elemental constituents. The output rate of emission lines allows projecting in a loop the elements as the cationic counterpart of the rock. In parallel, the Raman response of the unknown is compared with all the molecular counterparts of the hypothesized cation that are stored in a spectral library. The largest similarity rate unveils the final identity of the unknown. The identification capabilities of the architecture have been underscored through blind tests of 10 natural rocks with different origins. The great majority of forecasts have matched with the real identities of the inspected targets. The strength of this platform to simultaneously acquire the multielemental and the molecular information from a specimen by using the same laser events greatly enhances the "on-surface" missions for the surveillance of mineralogy.

“…However, owing to the need for a highly sensitive detector such as an ICCD spectrometer, the use of a pulsed laser for Raman analysis is expected to be limited in a portable system. Matroodi et al [ 49 ] reported the simultaneous recording of Raman and LIBS achieved with 5- and 35-mJ pulses generated by a single laser. However, the signal was acquired using an ICCD.…”

Hybrid Raman and Laser-Induced Breakdown Spectroscopy for Food Authentication Applications

et al. 2023

The issue of food fraud has become a significant global concern as it affects both the quality and safety of food products, ultimately resulting in the loss of customer trust and brand loyalty. To address this problem, we have developed an innovative approach that can tackle various types of food fraud, including adulteration, substitution, and dilution. Our methodology utilizes an integrated system that combines laser-induced breakdown spectroscopy (LIBS) and Raman spectroscopy. Although both techniques emerged as valuable tools for food analysis, they have until now been used separately, and their combined potential in food fraud has not been thoroughly tested. The aim of our study was to demonstrate the potential benefits of integrating Raman and LIBS modalities in a portable system for improved product classification and subsequent authentication. In pursuit of this objective, we designed and tested a compact, hybrid Raman/LIBS system, which exhibited distinct advantages over the individual modalities. Our findings illustrate that the combination of these two modalities can achieve higher accuracy in product classification, leading to more effective and reliable product authentication. Overall, our research highlights the potential of hybrid systems for practical applications in a variety of industries. The integration and design were mainly focused on the detection and characterization of both elemental and molecular elements in various food products. Two different sets of solid food samples (sixteen Alpine-style cheeses and seven brands of Arabica coffee beans) were chosen for the authentication analysis. Class detection and classification were accomplished through the use of multivariate feature selection and machine-learning procedures. The accuracy of classification was observed to improve by approximately 10% when utilizing the hybrid Raman/LIBS spectra, as opposed to the analysis of spectra from the individual methods. This clearly demonstrates that the hybrid system can significantly improve food authentication accuracy while maintaining the portability of the combined system. Thus, the successful implementation of a hybrid Raman-LIBS technique is expected to contribute to the development of novel portable devices for food authentication in food as well as other various industries.

“…Combining LIBS with Raman spectroscopy has increased the ability to identify unknown materials at stand-off distances through sensor-data fusion (Fig. 7 shows an example) [119,[193][194][195][196]. As high-energy lasers become more portable, the suitability of LIBS for use in the field is improving [168,184,197].…”

Advances in explosives analysis—part II: photon and neutron methods

View full text Add to dashboard Cite

The number and capability of explosives detection and analysis methods have increased dramatically since publication of the Analytical and Bioanalytical Chemistry special issue devoted to Explosives Analysis [Moore DS, Goodpaster JV, Anal Bioanal Chem 395:245-246, 2009]. Here we review and critically evaluate the latest (the past five years) important advances in explosives detection, with details of the improvements over previous methods, and suggest possible avenues towards further advances in, e.g., stand-off distance, detection limit, selectivity, and penetration through camouflage or packaging. The review consists of two parts. Part I discussed methods based on animals, chemicals (including colorimetry, molecularly imprinted polymers, electrochemistry, and immunochemistry), ions (both ion-mobility spectrometry and mass spectrometry), and mechanical devices. This part, Part II, will review methods based on photons, from very energetic photons including X-rays and gamma rays down to the terahertz range, and neutrons.
