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 ...

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 ...

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 ...

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.

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 ...

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...

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 ...

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 ...

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 ...

A new mass spectrometry technique sorts molecules to capture those of lower abundance. For scientists, a molecule’s weight can help determine its makeup. For measures like this, researchers turn to a ...
