Quantitative Analysis by Mass Spectrometry: Some Important Considerationssome time. Despite increased interest and activity in this area, there remains a paucity of published information detailing the key aspects of quantitative mass spectrometry. This chapter outlines some of the basic principles, but space limitations preclude a detailed coverage; instead, several of t

Role of Internal Energy in Mass Spectrometric Fragmentationckground: the reaction rate theory and the calculation of ion abundances from reaction rates. The effect of the reaction timescale, the degree-offreedom effect and the breakdown curve is discussed. Finally, typical internal energy distributions in electron impact, metastable ions, collision induced

Nevertheless, their high dynamic range, resolving power in the 10,000 range, exact-mass-measurement and high-energy-collisional-activation capabilities continue to recommend their use and improvement. This chapter is a review of analyses for which

Quadrupole Mass Filters and Quadrupole Ion Trapsmass analysis using quadrupole fields is described in conjunction with the various scan methods and operating parameters. The high performance of quadrupole ion traps is illustrated by introducing some new developments of the instrumentation, including mass range extension, high resolution, MS/MS ex
