Description
Sets a specific nebulizer gas pressure for the analysis,
based on the gas pressure specified for the nebulizer from
the nebulizer certificate.
As a standard, the Analytical mode is set.
For VH-D20 detector only:
Two modes for regulating the nebulizer gas pressure in
the detector are available: Analytical mode and MicroLC
mode.
For details on the gas regulation modes, see
Regulation Mode (VH-D20 Detector only)
Specifies the nebulizer gas pressure as specified on the
certificate that was shipped with the nebulizer.
Observe the notes in Setting the Nebulizer Gas Pressure
and the Nebulizer Serial Number
Displays the actual pressure of the gas supplied to the
nebulizer.
After you have set the nebulizer gas pressure, monitor the
GasRegPressure parameter until it reaches the setpoint.
Turns the detector gas flow On or Off.
Observe the notes in Turning On/Off the Detector Gas
Flow (} page 102).
Description
Temperature control for the evaporation tube is enabled
as a standard when the detector is shipped.
Specifies the setpoint for the evaporation temperature.
As a standard, the Evaporator Temperature Nominal is
set to 35 °C.
For further information, see
(} page 110).
Displays the actual temperature of the evaporation tube.
The actual temperature depends on several factors,
including mobile phase composition and temperature,
pump flow rate, gas temperature, and ambient
temperature.
As a standard, the temperature unit is °C.
