WebStep 2. Atoms are ionised (by firing electrons at them to knock out an outer shell electron) hence form positive ions. Step 3. Ions are accelerated by an electric field. Step 4. Ions stream then passes through a magnetic field which causes them to move in a curved pathway. Isotopes of different masses are deflected differently. WebHow HPLC detectors work. Most HPLC detectors work by converting a physiochemical property of an analyte into an electrical signal. In other words, a detector ‘sees’ a sample and sends signals at consecutive time points throughout the sample run. Signal intensity should correlate with the amount – either mass or concentration – of the ...
WebIon-trap methods. It is possible to configure electric and magnetic fields so that ions can be held in stable orbits for a period of time long enough to perform useful measurements on them. Two forms of mass spectrometers are derived from this idea, the omegatron and the Fourier-transform spectrometer. Both make use of the cyclotron principle ...
