Conventional mass spectrometers are typically very large, comparable in size to an oven or refrigerator. By using a technology called a “coded aperture,” the researchers believe they can shrink these ...

ATLANTA (February 8, 2006) -- Being the delicate optical instruments that they are, spectrometers are pretty picky about light. But Georgia Tech researchers have developed a technology to help ...

As a defense lawyer in Toronto, I read with interest “Portable Spectrometers Give On-Site Testing a Boost,” by Carolyn Wilke (C&EN, April 17/24, 2023, page 28). These new, often handheld, devices may ...

An illustration featuring a spectrometer with its scanner set on a bag of substances. The background features several geometric shapes and math symbols. The words "methamphetamine" and ...

CORVALLIS, Ore. – Scientists including an Oregon State University materials researcher have developed a better tool to measure light, contributing to a field known as optical spectrometry in a way ...

This notice is a combined synopsis/solicitation for commercial items prepared in accordance with the format in FAR Subpart 12.6, as supplemented with additional information included in this notice.

BYU researchers have created a miniaturized, portable version of a tool now capable of analyzing Mars’ atmosphere — and that’s just one of its myriad possible uses. For decades mass spectrometers have ...

The ultrabroadband infrared frequency comb could be used for chemical detection in portable spectrometers or high-resolution remote sensors. (Nanowerk News) Optical frequency combs are specially ...

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 ...
