Comparison of the Paul ion trap to the linear ion trap for use in global proteomics

Proteomics, 2006
AbstractA critical evaluation of the performance of a 2‐D linear ion trap (IT) instrument to two 3‐D quadrupole IT instruments with emphasis on identification of rat serum proteins by bottom‐up LC‐MS/MS is presented. The speed and sensitivity of each of the instruments were investigated, and the effects that each of these have on the bottom‐up ...

Ion Cloud Model for a Linear Quadrupole Ion Trap

European Journal of Mass Spectrometry, 2012
If large numbers of ions are stored in a linear quadrupole ion trap, space charge causes the oscillation frequencies of ions to decrease. Ions then appear at higher apparent masses when resonantly ejected for mass analysis. In principle, to calculate mass shifts requires calculating the positions of all ions, interacting with each ...
