Functional Description
Mass Spectrometer
22 TSQ Series Hardware Manual Thermo Scientific
• The Vent Valve Closed LED illuminates green whenever the vent valve current sensor
detects current through the vent valve and the vent valve is closed. The LED is off when
the vent valve is open.
• The Ethernet Link OK LED illuminates 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.
API Source
The atmospheric pressure ionization (API) source forms gas phase sample ions from sample
molecules that elute from the LC or are introduced by the syringe pump. You can operate the
API source in the electrospray ionization (ESI), heated electrospray ionization (H-ESI),
nanospray ionization (NSI), atmospheric pressure photo ionization (APPI), or atmospheric
pressure chemical ionization (APCI) mode. For more information regarding the API source,
refer to the Ion Max and Ion Max-S API Source Hardware Manual, HESI-II Probe User Guide,
H-ESI Probe User Guide, Ion Max APPI Source Operator’s Manual, or Nanospray Ion Source
Operator’s Manual.
Ion Source Interface
The ion source interface consists of the components of the API source that are held under
vacuum (except for the atmospheric pressure side of the ion sweep cone). The ion source
interface includes an ion transfer tube, two cartridge heaters, a heater block, a platinum probe
sensor, a vent prevent ball, and an ion sweep cone. See Figure 14.
CAUTION In an emergency, to shut off all power to the mass spectrometer, place the Main
Power circuit breaker switch (labeled Main Power) in the Off (O) position.
