Enhanced Molecular Ion in GC/MS by Cold EI - Trace Organic

11 Molecular Ion Dependence on Carbon Number • In Standard EI the molecular ion is reduced by ~20% per each added carbon • In Cold EI it is approximately size independent • The relative abundance of the molecular ion in Cold EI is significantly enhanced • The enhancement is exponentially increased with the carbon number up to a factor of 2500 for C
