For decades, bulky spectrometers have been the main tools for understanding how things are made of chemicals (a thing called composition). Spectrometers are a type of lab equipment that uses prisms or ...

Researchers are designing new ways to make spectrometers that are ultra-small but still very powerful, to be used for anything from detecting disease to observing stars in distant galaxies.

A good portable Raman spectrometer bridges the gap in capability, performance, and size between benchtop and handheld Raman spectroscopy. It allows new point-of-use applications in industry and ...

For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food quality, or analyzing pollution, depended on large, expensive laboratory ...

Researchers 3D printed a miniature ionizer, a key component of a mass spectrometer. Their device could someday enable an affordable, in-home mass spectrometer for health monitoring. Mass spectrometry, ...

This is a close-up view of the “spectrometer-on-a-chip” technology that could dramatically reduce the size of spectrometers in the future. (Credit: NASA Goddard/Chris Gunn) The Composite Infrared ...

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 ...

(Nanowerk News) Spectrometers are technology for reading light that date back to the era of famed 17th-century physicist Isaac Newton. They work by breaking down light waves into their different ...
