“…One of the interesting aspects of this technique is that this technique does not require standard samples and involves selfcalibration as well. The detailed explanation of this approach can be found in [11,24,25]. This procedure is based on the creation and acquirement of emission spectra of an unknown specimen for every element present in the sample and then the calculation of every emission line area [11].…”

“…The spectral emission from the laser generated plasma is used as a fingerprint wavelength, which assists the detection of the elemental composition of the target. In 2016, CF-LIBS approach was employed for the determination of elemental contents in potatoes [11]. This technique was successfully applied to measure the amount of minerals and toxic metals in calcified tissues [12].…”

Laser-induced breakdown spectroscopy (LIBS) was used for the quantitative analysis of elements present in textile dyes at ambient pressure via the fundamental mode (1064 nm) of a Nd:YAG pulsed laser. Three samples were collected for this purpose. Spectra of textile dyes were acquired using an HR spectrometer (LIBS2000+, Ocean Optics, Inc.) having an optical resolution of 0.06 nm in the spectral range of 200 to 720 nm. Toxic metals like Cr, Cu, Fe, Ni, and Zn along with other elements like Al, Mg, Ca, and Na were revealed to exist in the samples. The %-age concentrations of the detected elements were measured by means of standard calibration curve method, intensities of every emission from every species, and calibration-free (CF) LIBS approach. Only Sample 3 was found to contain heavy metals like Cr, Cu, and Ni above the prescribed limit. The results using LIBS were found to be in good agreement when compared to outcomes of inductively coupled plasma/atomic emission spectroscopy (ICP/AES).

“…The intensities of spectral emission lines observed in the spectrum can be used to measure the relative abundance of species in the sample [5]. Literature survey report the significant work using LIBS on the elemental analysis of materials including marbles [6,7], metals and ceramics [8], vegetables [9], crystals [10], pigments [11], and plant materials [12,13]. This method has been used for the elemental analysis fertilizers [14].…”

Laser-induced Breakdown Spectroscopy (LIBS) was used for the quantitative study of Shilajit samples using first harmonic (1064 nm) of a Q-Switched Nd:YAG laser by an appropriate detection system. The samples were chosen from the northern Himalayan mountainous range at locations namely Skardu, Gilgit, Chilas, Chitral, and Muzaffarabad. The relative concentrations of detected species were measured via integrated intensity of the strongest line of an element and via Calibration-Free CF-LIBS approach. Our findings recommend the altitudinal variations in Physico-chemical properties of Shilajit. Different functional groups were identified using Fourier Transform infrared (FTIR)-Spectroscopy. The results of LIBS were compared to results of Inductively Coupled Plasma/Optical Emission Spectroscopy (ICP/OES) with fine harmony.
