The ISVF parameter affects the stability of
the spray and hence the signal sensitivity.
This is the voltage applied to the needle that
sprays the sample.

The IHT parameter controls the temperature
of the NanoSpray
®
interface heater and is
only available if the NanoSpray
®
ion source
and interface are installed.
The optimal heater temperature depends on
the type of sample being analyzed and the
solvent used. If the heater temperature is
too high, the signal degrades. Typically,
heater temperatures are in the 130 °C to
180 °C range. The maximum heater
temperature that can be set is 250 °C, but
this is too high for most applications.
