Description: Bendix MA-2 Time-of-Flight Mass Spectrometer with female model General view of a Bendix MA-2 Time-of-Flight Mass Spectrometer with a female model. The Time-of-Flight Mass Spectrometer (TOFMS) was the flagship analytical instrument of the Bendix Corporation. Mass spectrometry is an analytical technique used to identify qualitatively and quantitatively the atomic and molecular composition of inorganic and organic materials by sorting ions according to their mass-to-charge ratios. Mass spectrometers consist of four basic parts: a handling system used to introduce the unknown sample into the equipment; an ion source, in which a beam of particles characteristic of the sample is produced; an analyzer that separates the particles according to mass; and a detector, in which the separated ion components are collected and characterized. Published without a copyright notice in a Bendix MA-2 Time-of-Flight Mass Spectrometer trade publication (a copy is in the Institute collections); accordingly, photo is in the public domain in the U.S. due to failure to comply with required formalities.
