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 ... 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. list of stephen hunter books in order
