1
IS (IonSpray
Voltage)
Source and
gas
The IS parameter controls the
voltage applied to the electrode that
ionizes the sample in the ion source.
It depends on the polarity and it
affects the spray stability and the
sensitivity. This parameter can be
compound-dependent and should be
optimized for each compound.
All
1
NC (Nebulizer
Current)
Source and
gas
The NC parameter controls the
current applied to the corona
discharge needle in the APCI probe,
used in the Turbo V™ ion source.
The discharge ionizes solvent
molecules, which in turn ionize the
sample molecules.
All
1
ihe (Interface
Heater)
Source and
gas
The ihe parameter turns the interface
heater on and off. Heating the
interface helps maximize the ion
signal and prevents contamination of
the ion optics. The interface heater
should always be on. The button
controlling the interface heater reads
ON when the interface heater is on.
All
1
IHT (Interface
Heater
Temperature)
Source and
gas
The IHT parameter controls the
temperature of the NanoSpray
®
interface heater and is only available
if the NanoSpray ion source and
interface are installed.
All
1
sdp
Source and
gas
The sdp parameter controls the
selection of the DuoSpray™ ion
source probes: TurboIonSpray
®
probe or APCI probe.
