Detailed explanation of CI and NCI
Model
There are three types of QP2010 dependent on the types of ionization.
Ver. 2.1 of the GCMSsolution is required to use the CI, NCI, and DI option.

Major different points from 5050A
EI and CI (SEI, SCI) can be simulated using the NCI ion source (for the NCI equipped model
only)
Simulated CI (SCI) mode
in NCI ion source is added.
Ionization mode can be selected from SEI, SCI and NCI by indication from PC in NCI ion
source.
Note : SEI in CI ion source is not available.
Selection of reagent gases
QP2010 has
two inlet lines
for reagent gas.
Selection of reagent gas
is available from two
types of gas by switching the inlet line from PC.
RP2 is unnecessary for CI and NCI
The rotary pump, which is a backing pump for TMPs, evacuates the reagent gas line at the
same time.
