[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 ...

New research published the journal Biomedical Optics Express describes a smartphone-compatible spectrometer held and directed like a pencil. According to the article's authors, this novel device could ...

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 ...

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 ...

Researchers have successfully demonstrated a spectrometer that is orders of magnitude smaller than current technologies and can accurately measure wavelengths of light from ultraviolet to the ...

Researchers have devised a novel and simple method to measure nano/microplastic concentrations in soil using spectroscopy at two wavelengths A team of researchers has developed a novel and simple ...

A spectrometer is an instrument that is often employed to examine, identify, and precisely gauge electromagnetic radiation emanating from a substance. This aids in identifying the elemental ...

Color, as the way light's wavelength is perceived by the human eye, goes beyond a simple aesthetic element, containing important scientific information like a substance's composition or state.

Photoionization mass spectrometry has transformed analytical chemistry, enabling complex chemical analysis and celebrating a century of scientific progress.
