For decades, bulky spectrometers have been the main tools for understanding how things are made of chemicals (a thing called ...

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 ...

A spectrometer is one of those tools that many of us would love to have, but just can’t justify the price of. Sure there are some DIY options out there, but few of them have the convenience or ...

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 ...

As much as we know today about the planets of the solar system, it’s almost incomprehensible that a mere 50 years ago we knew almost nothing about them. Observations of even Mars and Venus, Earth’s ...

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 ...

A new mass spectrometry technique captures molecules of lower abundance in a sample, providing a more comprehensive sample profile.

Researchers 3D printed a mini quadrupole mass filter, a key component of a mass spectrometer, that performs as well as some commercial-grade devices. It can be fabricated in hours for a few dollars ...
