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 ...

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 ...

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, ...

For electrical engineers working in almost any part of the wired or wireless spectrum, the spectrum analyzer is a critical test and measurement tool. For optical engineering, the equivalent tool is ...
