NCI: When analysis is done without switching the NCI and EI ion source, don't some results deteriorate compared to normal EI?
The sensitivity of EI done with the NCI ion source is not as good. When the S/N of standard samples is compared, the level of the NCI ion source is about 1/5 that of the standard EI ion source.
