NASA's mass spectrometer sits aboard a DC-8 jet to be used as a flying lab that will study the impact of air pollution on the Arctic area. David McNew/Getty Images The worlds of analytical chemistry and major league baseball would seem to be a million miles apart. But in the ...
We can limit the amount of colours in our rainbow. You can also do this with a bit of food colouring and water in a clear glass. Try a few colours and guess which colours will or won't be shown in the projected rainbow. This is pretty much how a spectrometer works...
Mass spectrometry (MS) is an analytical laboratory technique to separate the components of a sample by theirmassand electrical charge. The instrument used in MS is called mass spectrometer. It produces a mass spectrum that plots the mass-to-charge (m/z) ratio of compounds in a mixture. How ...

10K Mass spectrometry is a substance from a crime scene that is analyzed by a mass spectrometer in order to find the molecular makeup. Explore how mass spectrometry can be used to identify all kinds of evidence such as cloths, glass, dyes, metals, and even human tissue. Related...
Explain how a mass spectrometer works. Describe how volatile compounds can be separated by gas chromatorgprahy. Make sure to discuss stationary and mobile phases. Describe a unit cell as precisely as possible. Describe what is inside the al...
The ‘1' being a proton added in the ionization process [represented M+H+ or M-H- if formed by the loss of a proton] or if the ion is formed by loss of an electron it is represented as the radical cation [M+.]. The accuracy of a mass spectrometer or how well it...
A spectrophotometer is a device used to measure light at a specific wavelength. It consists of two parts: a spectrometer and a photometer. The spectrometer provides light at a specific wavelength. The photometer measures how intense the light is. By calculating the amount of light that a solut...
are still an issue for space applications,” said Ji. “For example, four spectrometer modules for the future advanced space mission SAFARI-SPICA have a maximal physical size varying from 0.4 to 0.5 meters. The spectrometer becomes even more bulky and heavier when it aims to operate ...
electric currents were passed through tubes containing gaseous elements (hydrogen, helium, neon) and when elements were heated (e.g., sodium, potassium, calcium, etc.) in a flame. They passed the light from these sources through a spectrometer (a device containing a narrow slit and a glass ...
