Spectrometric Techniques for Combinatorial Compound Analysis

2 Mass Spectrometric Techniques for Combinatorial Compound Analysis 

1 Ionization Techniques A range of these techniques is available  

Preferably, electrospray ionization (ESI) is used in combination with quadrupole mass filters [16,17], whereas MALDI is commonly used in combination with the time-of-flight (TOF) analyzer [18], The relatively simple construction of these two types of analyzers and the resulting price advantage has led to their replacing the traditional magnetic sector instruments as the workhorses of mass spectrometric analysis. A more recent development is the ion-cyclotron-resonance (ICR) analyzer [19] which can be used for both ES-and MALDI-ionization.
