High-Resolving Mass Analyzers

Abstract

AbstractFirst high-resolving mass analyzers were built ≈80 years ago as sector field systems, well reproducible ones, however, only much later. Besides these sector-field systems there are three other types of mass analyzers: (1) Penning trap mass analyzers, have achieved the highest resolving powers, but require big technological efforts. (2) Time-of-flight mass analyzers have become the most versatile systems, while high performing multi-reflection time-of-flight systems have only started to be used. (3) Fourier Transform and Orbitrap mass analyzers have achieved spectacularly high mass resolving powers, but are also technically demanding and difficult to build systems.
