Spectroscopy seems simple: split a beam of light into its constituent wavelengths with a prism or diffraction grating, and measure the intensity of each wavelength. The devil is in the details, though ...

A complete walkthrough of a DIY spectrometer upgrade project, covering the limitations of the original $60 device, the addition of an optical fiber input, and the key lessons learned about sensitivity ...

Laser-induced breakdown spectroscopy (LIBS) enables the direct measurement of cell electrolyte concentrations. The utility of LIBS spectra in biomarker studies is limited because these studies rarely ...

In this study, several types of metals were tested for identification based on their spectral lines. Laser Induced Breakdown Spectroscopy (LIBS) is a type of atomic emission spectroscopy which ...
