Spectrometer testing
WebAn energy-dispersive spectrometer can determine the quantity and energy of X-rays released from a specimen. EDS enables the measurement of the specimen’s elemental composition since the energies of the X-rays are … WebJun 8, 2024 · The technology had its start 60 years ago in Midland, Michigan, with the pairing of two powerful analytical techniques — gas chromatography (GC) and mass spectrometry (MS). By coupling the ability of GC to separate a chemical mixture with the ability of MS to identify its components, the new, combined technique proved revolutionary.

WebAug 15, 2024 · Stage 1: Ionization: The atom is ionised by knocking one or more electrons off to give a positive ion. This is true even for things which you would normally expect to form negative ions (chlorine, for example) or never form ions at all (argon, for example). Mass spectrometers always work with positive ions.
