A Simple LIBS (Laser-Induced Breakdown Spectroscopy) Laboratory Experiment to Introduce Undergraduates to Calibration Functions and Atomic Spectroscopy
Chinni, Rosemarie C.
Journal of Chemical Education, v89 n5 p678-680 Apr 2012
This laboratory experiment introduces students to a different type of atomic spectroscopy: laser-induced breakdown spectroscopy (LIBS). LIBS uses a laser-generated spark to excite the sample; once excited, the elemental emission is spectrally resolved and detected. The students use LIBS to analyze a series of standard synthetic silicate samples that contained various elements at known concentrations. The students gain valuable experience developing calibration curves to determine sensitivity and detection limits for six elements in these samples. This experiment is applicable to an analytical or instrumental analysis course. (Contains 1 figure and 2 tables.)
