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...
A mass spectrometer is an instrument which ionizes a sample, separates the ions depending on their mass-to-charge ratio, and measures the intensity of the ions present at different mass-to-charge ratios. This can be used to determine the elements or isotopes present in the sample. The techni...
A spectrometer is a device that measures a continuous, non-discrete physical characteristic by first separating it into a spectrum of its constituent components.
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 ...

What is a mass spectrometer? How does it work? What makes an OH group stretch broad on an IR spectrum? What is spectroscopy? What are the different methods of spectroscopy? What information do we get from a formula? From an equation?
In the broadest sense a spectrometer is any instrument that is used to measure the variation of a physical characteristic over a given range; i.e. a spectrum. This could be a mass-to-charge ratio spectrum in the case of a mass spectrometer, the variation of nuclear resonant frequencies in...
A component called a reflectron, which directs the incoming ions at the ion detector, is often incorporated into the mass spectrometer. When the ions strike the detector, it records the event as well as the charge of the ion and the elapsed time in flight between the ion generator and the...
