ABSTRACT
Mass analyzers are varied significantly in their mode of operation and design architecture; the following section provides a brief technical overview of the different types of mass analyzers in use today in relation to gas chromatography (GC) and volatile organic compounds (VOCs) analysis. The first part of the chapters also covers the mechanism of separation involved conventional GC, from idealized plate theory to the Van Deemter Equation, exposing the reader to core concepts in GC. While the second part of the chapter gives an overview of several different mass analyzers and their respective mode of operations, from single quadrupole mass filters (QMF) to triple quadrupoles (QQQ), time of flight (TOF), quadrupole 32time of flight (qTOF) and Orbitrap Mass analyzers, the description is not mean exhaustive and readers are encouraged to explore further with the reference provided within the chapter.
