INTRODUCTION Mass spectrometry (MS) is an analytical technique that measures the mass-to-charge particles. 0000006883 00000 n /Size 205 3 0 obj Ions are deflected by a magnetic field due to difference in their masses. b) In all cases this involves manipulation of a charged particle in electric and/or magnetic fields. Different Mass Analyzers A mass analyzer is the component of the mass spectrometer that takes ionized masses and separates them based on charge to mass ratios and outputs them to the detector where they are detected and later converted to a digital output. r. e. r. m.
