GC/MS CI , CI/NCI and SMCI Measurement
CI is a softer ionization method than EI, fragmentation is less likely to occur, so molecular weight information is more readily obtained. Negative chemical ionization (NCI) or negative ion chemical ionization (NICI) enables selectively measuring, with ultra high sensitivity, chemical substances with an electron affinity, such as chlorine-based compounds.
