Mass spectrometry (MS) as we know it today is a result of technological advancements of the pioneering work of three remarkable men – Wilhelm Wien, J.J. Thomson and Francis Aston. If one were to ...

How does Membrane Inlet Mass Spectrometry Work? Membrane Inlet Mass Spectrometry (MIMS) relies on the principles of mass spectrometry and the selective permeability of membranes that allow the passage ...

How does a spectrometer work? In spectroscopy, photons encounter many components and undergo a variety of processes before registering as a spectrum. Let's see what happens to these photons once they ...

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 ...

The Planetary Fourier Spectrometer (PFS) on board ESA’s Mars Express spacecraft is now back in operation after a malfunction, reported a few months ago. The instrument had been successfully ...
