Before a spectrometer can do any useful work, it needs to be calibrated to identify wavelengths correctly. This is usually done by detecting several characteristic peaks or dips in a well-known light ...

A new electron paramagnetic resonance (EPR) spectrometer aims to open the technology to a larger pool of scientists by making it cheaper, lighter, and easier to use without needing an experienced ...

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 ...

University of Illinois chemistry professor Alexander Scheeline wants to see high school students using their cell phones in class. Not for texting or surfing the Web, but as an analytical chemistry ...

Spectrometer optics involves measuring light intensity by means of a specialized analytical tool called a spectrometer which separates light by wavelength. Spectrometers are used for a variety of ...
