“…LIBS is an elemental spectroscopy technique that uses a focused laser beam to create a plasma on the target sample, which can be solid, liquid, gas, or aerosol. [25][26][27][28] Collection and wavelength dispersion of the light emitted by the plasma allows qualitative and quantitative elemental measurements. Noninvasive, in-situ, and real-time multielement detection of gas and aerosol samples are LIBS most notable advantages.…”

Laser-induced breakdown spectroscopy (LIBS) was used to characterize the materials released by lithium-ion (Li-ion) cells at thermal runaway conditions. Commercial AAA-size, rechargeable, 3.7-V, 350-mAh, Li-ion battery cells were heated in a N2-atmosphere tubular chamber up to about 165 Â°C to induce thermal decomposition. Through measurements of the chamber internal temperature and LIBS emission intensities over time the onset temperature of thermal runaway (â143 Â°C) and the duration of the cells outgassing (> 40 minutes) were determined. Relatively high intensity atomic emissions from C, H, F, Li, Na, and P were detected at different times during the heating experiments. The detection of analytes such as C and H was continuous over time. On the contrary, detection of F, Na, Li, and P was more irregular, indicating the presence of solid-phase analytes or analyte-bearing particles. A calibration scheme for estimation of the total mass/volume concentration of all carbon-based species sampled within the laser-induced plasma was developed.

“…Air absorbs more energy to create longer-lasting air plasmas because its energy absorption cross-section is much larger than that of particles (air volume is significantly greater than particle volume at the focus point). The air plasma will be employed as a secondary excitation source to dissociate the particle plasma after the laser pulse. ,, …”

“…The air plasma will be employed as a secondary excitation source to dissociate the particle plasma after the laser pulse. 23,36,39 Figure 6 and Supporting Information (Figures S6 and S7) show the time evolution of various elements in air plasma and particle plasma. When the plasma starts to cool (10−200 ns), ion lines O II and N II first start to be generated, and the ion line SNR achieves the highest value at about 100 ns.…”

The attribution of single particle sources of atmospheric aerosols is an essential problem in the study of air pollution. However, it is still difficult to qualitatively analyze the source of a single aerosol particle using noncontact in situ techniques. Hence, we proposed using optical trapping to combine gated Raman spectroscopy with laserinduced breakdown spectroscopy (LIBS) in a single levitated micron aerosol. The findings of the spectroscopic imaging indicated that the particle plasma formed by a single particle ablation with a pulsed laser within 7 ns deviates from the trapped particle location. The LIBS acquisition field of view was expanded using the 19-bundle fiber, which also reduces the fluctuation of a single particle signal. In addition, gated Raman was utilized to suppress the fluorescence and increase the Raman signal-to-noise ratio. Based on this, Raman can measure hardto-ionize substances with LIBS, such as sulfates. The LIBS radical can overcome the restriction that Raman cannot detect ionic chemicals like fluoride and chloride in halogens. To test the capability of directly identifying distinctive feature compounds utilizing spectra, we detected anions using Raman spectroscopy and cations using LIBS. Four typical mineral aerosols are subjected to precise qualitative evaluations (marble, gypsum, baking soda, and activated carbon adsorbed potassium bicarbonate). To further validate the application potential for substances with indistinctive feature discrimination, we employed machine learning algorithms to conduct a qualitative analysis of the coal aerosol from ten different origin regions. Three data fusion methodologies (early fusion, intermediate fusion, and late fusion) for Raman and LIBS are implemented, respectively. The accuracy of the late fusion model prediction using StackingClassifier is higher than that of the LIBS data (66.7%) and Raman data (86.1%) models, with an average accuracy of 90.6%. This research has the potential to provide online single aerosol analysis as well as technical assistance for aerosol monitoring and early warning.

“…One of the main LIBS advantages include the high working speed compared to other techniques. LIBS applications to aerosol analysis have been reported previously [26,[31][32][33], however, to the best of our knowledge, we were the first to demonstrate LIBS scanning microanalysis potential use for characterizing ambient air aerosol particles deposited on filters.…”

“…Although being an analytical challenge due to its wide variation in aerosol particles [26], the full visualization of PM internal composition is demanded to better comprehend PM potential sources and interactions. This is particularly the case of our Antarctic PM filters, with an expected low PM concentrations compared to urban areas.…”
