LIBS; FTIR Spectroscopy; Calcium Oxalate; Kidney Stones; Mineral Elements;

In the present work, spectroscopic investigations have been performed on a kidney stone to determine its chemical composition using Fourier transform infra-red (FTIR) spectroscopy and laser-induced breakdown spectroscopy (LIBS). Fourier transform infra-red (FTIR) spectroscopy were used to classification of stone's type and also to determine its minor constituents. Using FTIR spectroscopy, we have detected calcium oxalate as a major constituent of kidney stone and hence classified as oxalate stone. We have also observed the presence of calcium carbonate in calcite form and calcium phosphate in the kidney stone sample. LIBS has been used to detect the elemental content of kidney stone which were calcium (Ca), silicon (Si), tin (Sn), potassium (K), magnesium (Mg), iron (Fe), copper (Cu), titanium (Ti), fluorine (F), carbon (C), and nitrogen (N). This paper demonstrates FTIR and LIBS as a promising, simple, and accurate analytical method to study kidney stones.
