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 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...
Multiple charging extends the range of the mass spectrometer well beyond its designed upper limit to include masses of 1,000,000 Da or more.Isotope and elemental mass spectrometry Natural isotope abundance is well-characterized. Though often thought to be stable, it can nevertheless dis...
on a sample of molecules and then sorting the ions based on their mass-to-charge ratio. Since the particle has a one electron negative charge or one proton positive charge, the mass spectrometer can make use of electrical and/or magnetic fields to essentially sort molecules by their masses. ...
In order to make a qualified judgement of the ion optical properties of a time-of-flight system, it is necessary to have a method of presentation that does not require an extensive background in ion optical theory to understand it. The authors present such a method. This method gives a mo...
