Spectral images, which contain more color information than is obtainable with a typical camera, reveal characteristics of tissue and other biological samples that can’t be seen by the naked eye. A new ...

[Project 326] wanted to know exactly what gas was in some glass tubes. The answer, of course, is to use a spectrometer, but that’s an expensive piece of gear, right? Not really. Sure, these cheap ...

The composition of complex mixtures of molecules can be determined using NMR spectroscopy. Each of the thin glass tubes is filled with an extract of sea water that contains a few milligrams of ...

A spectrometer is a pretty common lab instrument, useful for determining the absorbance of a sample across a spectrum of light. The standard design is simple; a prism or diffraction grating to break ...

Researchers at the NC State University have successfully demonstrated a spectrometer that is orders of magnitude smaller than current technologies. Research team develops small spectrometer Credit: ...
