The elemental composition of the carrot root was investigated by the laser induced breakdown spectroscopy by recording its emission spectrum. The recorded spectrum of carrot root pellet showed the presence of atomic lines of inorganic element as potassium (K), sodium (Na), iron (Fe), calcium (Ca), titanium (Ti), zinc (Zn), mercury (Hg), copper (Cu), magnesium (Mg), strontium (Sr), and cobalt (Co) while spectrum of fresh raw carrot depicted additional organic element as carbon (C), hydrogen (H), nitrogen (N) and oxygen (O). The produced plasma was characterized by characteristic parameters like plasma temperature, electron density, Lorentz fitting etc.
