Description
The default unit setting for the gas pressure corresponds
to the Pressure Unit that is defined on the detector
configuration pages in the Chromeleon software.
Specifies the nebulizer gas pressure as specified on the
certificate that was shipped with the nebulizer.
Observe the notes in section 6.5.2 Verifying the Nebulizer
Gas Pressure, page 98.
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.
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-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
Gas Regulation Mode, page
Defines the width of a chromatographic peak at the half of
the peak height. Specify a peak width for the narrowest
expected peak in your chromatogram.
As a standard, when you set the Peak Width, Chromeleon
automatically calculates values for the Data Collection
Rate and the Filter Constant.
Defines the number of data points per second (Hz) that
the Chromeleon software collects from the detector and
stores as raw data.
For further information, see
Rate and Filter Constant, page
Applies a filter constant to the output current to
electronically reduce the baseline noise during the
analysis.
