EI CI Ion Source

Thermo Scientific
The Ethernet Link OK LED is green when the System Control PCB is communicating with
the data system PC. The LED is off when there is no communication between the System
Control PCB and the data system PC.
Electronics
The ion source forms gas phase sample ions from sample molecules that elute from the GC or
are introduced by the direct sample probe. You can operate the ion source in either the
electron ionization (EI) or chemical ionization (CI) mode. See
