Analysis of trace elements in liquids using laser induced breakdwon spectroscopy.ANALYSIS OF TRACE ELEMENTS Trace elements A group of elements that are present in the human body in very small amounts but are nonetheless important to good health. They include chromium, copper, cobalt, iodine, iron, selenium, and zinc. Trace elements are also called micronutrients. IN LIQUIDS USING LASER INDUCED BREAKDWON SPECTROSCOPY. Akshaya Kumar, Prakash C. Sharma, Department of Physics, College of Engineering, Architecture and Physical Sciences, Tuskegee University Tuskegee University, at Tuskegee, Ala.; coeducational; chartered and opened 1881 by Booker T. Washington as Tuskegee Normal and Industrial Institute. It became Tuskegee Institute in 1937 and adopted its present name in 1985. , Tuskegee, Alabama 36088. Laser induced breakdown spectroscopy (LIBS LIBS Laser Induced Breakdown Spectroscopy ) is a online and real time measurement technique for detection of trace elements. This technique works for any liquid, solid or gas samples. In this technique, a laser beam is tightly focused on the surface of sample. Strong electric field of the laser light creates plasma of the sample in the focused area of the beam. The spectrum of the plasma plume created by laser beam gives signature of the elements present in the sample which is recorded using a spectrometer. Using calibration curve it is possible to detect the concentration of trace elements. The LIBS measurement of elements present in water sample would be presented. |
