In order to measure the characteristics of individual molecules, a mass spectrometer converts them to ions so that they can be moved about and manipulated by external electric and magnetic fields. The three essential functions of a mass spectrometer, and the associated components, are:
A photon of frequency f and wavelength has the energy Î» = c/fE = hf = hcÎ»p = hÎ» Soâ¦ how do smoke detectors work? Schematic diagram:How it works:Light is scattered off the smoke particles and strikes the photosensitive cell.A small current is produced in the cell, triggering an alarm.
