Journal ArticleDOI
Prospects for laser-induced breakdown spectroscopy for biomedical applications: a review.
Vivek K. Singh,A. K. Rai +1 more
TL;DR: The unique abilities of LIBS including detection of molecular species and calibration-free LIBS are compared with those of other conventional techniques including atomic absorption spectroscopy, inductively coupled plasma atomic emission Spectroscopy and mass spectroscope, and X-ray fluorescence.
Journal ArticleDOI
Silicon-mediated alleviation of Cr(VI) toxicity in wheat seedlings as evidenced by chlorophyll florescence, laser induced breakdown spectroscopy and anatomical changes.
Durgesh Kumar Tripathi,Vijay Pratap Singh,Sheo Mohan Prasad,Devendra Kumar Chauhan,Nawal Kishore Dubey,A. K. Rai +5 more
TL;DR: The results showed the suitability of chlorophyll fluorescence as a parameter and appropriateness of LIBS technique and anatomical procedures to elucidate Si-mediated alleviation of Cr(VI) toxicity, and suggest that the measured parameters and techniques can be used non-invasively for monitoring the growth of crops under different environmental conditions.
Journal ArticleDOI
LIBS-an efficient approach for the determination of Cr in industrial wastewater.
Nilesh K. Rai,A. K. Rai +1 more
TL;DR: LIB spectra of different water samples having varying concentration of Cr have been recorded by using liquid jet configuration and it is found that calibration curve for Cr II (283.5 nm) atomic line is the best in terms of the Limit of detection (LOD) which is found to be 30 ppm.
Journal ArticleDOI
Laser-induced breakdown spectroscopy of molten aluminum alloy
TL;DR: The results suggest that the LIBS probe is useful for monitoring the elemental composition of an Al melt in an industrial furnace at different depths and different positions inside the melt.
Journal ArticleDOI
Assessment of LIBS for Spectrochemical Analysis: A Review
TL;DR: In this article, a review assesses the applications of laser-induced breakdown spectroscopy (LIBS) for the analysis of a variety of samples, including biomaterials (teeth, nail, hair, gallstones, and kidney stones), food materials (fruits and vegetables, milk, salt, nutritional supplements, etc.), medicinal plants, industrial waste, liquid samples, etc.
