The ions are detected by a mechanism capable of detecting charged particles, such as an electron multiplier.
(Other analyzer types are treated below.) Consider a sample of sodium chloride (table salt).Mass spectrometry (MS) is an analytical technique that measures the mass-to-charge ratio of ions.The results are typically presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio.The detector measures the value of an indicator quantity and thus provides data for calculating the abundances of each ion present.Some detectors also give spatial information, e.g., a multichannel plate.

The term mass spectroscope continued to be used even though the direct illumination of a phosphor screen was replaced by indirect measurements with an oscilloscope. Sector mass spectrometers known as calutrons were developed by Ernest O.
